Sony A7R II: Night Shooting (Coastal Optics 60mm f/4 UV-VIS-IR APO Macro)

I wanted to assess night-time performance of the Sony A7R II, my concern being issues with image quality in the 4-30 second range.

I also wanted perfect neutrality for out of focus areas, so I elected to use the Coastal Optics 60mm f/4 UV-VIS-IR APO MACRO, because the Coastal 60/4 is the best corrected lens for color that exists (that one can buy), consisting mostly off fluorite elements. Leica APO lenses do not even remotely approach its level of color correction, and even Zeiss Otus takes 2nd place to the Coastal (in color correction).

As it turns out, the image quality is stunning*. And the focusing experience on the Sony A7R II is second to none. It has been such a pain in the ass on Nikon and Canon that it had been a long time since I shot it, but the A7R II is so much more enjoyable and fast to use it that it it’s going back into the “always take it” bag. Moreover it is relatively small and light, albeit f/4. My main gripe is limited focus throw.

These images are cross-posted in two of my publications, because the coverage is both lens and camera review (a rare exception to the rule). So choose the appropriate link if subscribed to DAP or Mirrorless only.

The upshot of all of it is that (a) the Coastal 60/4 is simply amazing on the Sony A7R II, and (b) I found zero image quality issues with the Sony A7R II and came away very impressed.

Reader Question: Sony A7R II with Zeiss 135mm f/2 APO-Sonnar

See my review of the Zeiss 135mm f/2 APO-Sonnar in Guide to Zeiss.

Peter G writes:

I'd love to see your thoughts on the Zeiss 135mm APO lens (and possibly other ZE/ZF.2 lenses) on the A7rII platform.

I am very close to purchasing the 135mm APO for my A7rII and would love to hear your input. Would you recommend the ZE or ZF.2 for use on an E-Mount camera?

DIGLLOYD: the Zeiss 135mm f/2 APO-Sonnar should perform brilliantly—no reason it would not. The main concern is the weight; it’s a heavy lens and when extended by a lens adapter off the mount, that is quite a torque on the mount. So support that weight at all times by supporting the lens when handholding, and by using the Novoflex with ASTAT adapter when on a tripod (Metabones has an adapter too, but it cannot rotate vertical/portrait, or so I am told). Do not let that lens mount carry the torque on its own.

You'll have to manually open/close the aperture to focus and shoot, so this is not a fast operating lens for portraits and such. But I see that as a plus given the brain dead behavior of the A7R II when magnified: the Sony A7 series have no way to change exposure when in magnified view; the dials that ought to control shutter and aperture instead scroll the magnified image*. The Setting Effect = On/Off is useless because the camera stops down the lens if it’s bright, regardless of that setting, so it is flaky/unreliable. But with a manual aperture ring, all that disappears as a headache. Well, not the shutter speed, but it’s half a fix. So I would strongly recommend the ZF.2 version, which can be shot on Nikon (natively) or Canon (with adapter), and other platforms.

Get the Zeiss ZF.2 135mm f/2 APO-Sonnar for $300 off and 4% reward at B&H Photo (effective price = $1749 = a raging bargain). Ditto for Zeiss ZE 135mm f/2 APO-Sonnar for Canon (but no aperture ring on the ZE version).

* One of numerous reasons I have said that the Sony does not understand photography and that the design feels like a gadget, not a camera.

If you don't have Nikon DSLR (I sold my D3 2 years ago) the better choice is the ZE version. I ordered the Otus 85mm and the Zeiss Macro-Planar 2/100 in ZE mount and use it on a Metabones adapter.

You have full control of the aperture and shooting portraits is great with open aperture as it has been with DSLR before.

Using a high speed lens with manual aperture for studio portraits with f/8 for example is just useless with a manual aperture!

DIGLLOYD: it is not this simple.

First, “don’t have” can change over time.

Second, the Nikon F-mount is by far the most versatile mount: F-mount lenses (Zeiss ZF.2) can be used on Canon, Leica M, all mirrorless variants, various specialty gear, etc. Without an aperture ring, a Canon-mount lens is restricted to only those systems which have electronic adapters, and some of those suck. So the choices are more narrow (and generally more expensive).

The issue for my use with manual focus is that the A7R II (and its siblings) stop down the lens when the light gets bright, even with Setting Effect = OFF (see also my recommended settings for the A7R II and recommended customization for the Sony A7R II). I have tested and confirmed this problematic behavior using native lenses which I wished to focus manually at full aperture—not possible in bright light due to this stop-down behavior.

The Metabones adapter does not have a vertical (portrait) option for tripod use.

It is not possible (and never will be) to use the ZE version on Nikon (or any other DSLR) because of its flange distance (2mm longer than Nikon). So if one ever shoots or might shoot Nikon, those ZE and EF lenses are useless. But the Nikon version can be used on Canon and any mirrorless and Leica M and so on, as noted above, and with relatively inexpensive mechanical adapters. And I *prefer* manual aperture control (as might video shooters) for many purposes.

But to Dierk T’s valid albeit restricted use case: *if* you are shooting handheld and *if* the light is moderate and *if* tripod use is not the goal (portrait orientation) and *if* you have no intention of ever shooting Nikon, then the ZE version with Metabones adapter is indeed a fine choice.

Finally, there is no technical reason that a Nikon adapter could not work electronically like the ZE version: the Zeiss ZF.2 lenses use an electronic aperture control after all (I never use the aperture ring on my Nikon DSLR). So I maintain that the ZF.2 version is the best long term investment, particularly if/when the adapter allows it to act with electronic aperture controlled by the camera (maybe this already exists).

Studying Old Lenses on the Sony A7R II: Voigtlander 90mm f/3.5 APO-Lanthar and Voigtlander 180mm f/4 APO-Lanthar

I’ve added to my review of Voigtlander DSLR lenses* by studying two of the best on the Sony A7R II (as a convenient platform**, since could be done as well on Canon 5DS R). I’m pondering whether to expand that study to the Canon 5DS R (that depends on interest as these are specialty lenses).

The Voigtlander 180mm f/4 APO-Lanthar is one of the best corrected APO lenses around—not even Leica APO lenses approach its level of correction. The Voigtlander 90mm f/3.5 APO-Lanthar also has a high level of color correction. So I thought it would be interesting to study these two and then a few other lenses.

Announced: Canon 35mm f/1.4L II

Get Canon 35mm f/1.4L II USM at B&H Photo.

The Canon 35mm f/1.4L was a good design, but showed serious limits on modern digital. Along comes the new “II” design with some intriguing new optical prowess.

At about $1799, the Canon EF 35mm f/1.4L II USM looks to take care to offer improved image quality, particularly color correction:

The EF 35mm f/1.4L II USM from Canon is an L-series prime wide-angle lens featuring Blue Spectrum Refractive Optics and a maximum aperture of f/1.4, making it ideal for shooting in low-light situations and for controlling depth of field.

Two aspherical elements and one Ultra Low Dispersion (UD) element combine with the BR element to control chromatic aberrations and color fringing for increased clarity and sharpness.

A Subwavelength Coating has also been applied to reduce ghosting and lens flare for greater color accuracy and contrast.

The Ultrasonic autofocus motor (USM) provides fast and near-silent AF operation. Full time manual focus override enables precise manual focus even when in AF mode.

  • Prime wide-angle lens is designed for full-frame Canon EOS DSLRs, and can also be used with APS-C-sized sensors where it will provide a 56mm equivalent focal length.
  • The Blue Spectrum Refractive Optics element refracts shorter wavelengths of the visible spectrum (blue light) in order to significantly reduce chromaticaberrations and color fringing.
  • A pair of aspherical elements and one UD element also help to control aberrations and distortions for sharper, clearer image quality.
  • Subwavelength Coating minimizes surface reflections, ghosting, and flare for increased contrast and color fidelity.
  • The Ultrasonic Motor offers fast and quiet autofocus performance and also permits full-time manual focus control by simply rotating the focusing ring.
  • A minimum focus distance of 11" with a 0.21x maximum magnification benefits working with close-up subjects.
  • Fluorine coatings on the front and rear surfaces help reduce fingerprints and smudging.
    Featuring the L-series designation, this lens is also dust and moisture-resistant for use in trying conditions.
  • A nine-blade aperture provides smooth and pleasing out-of-focus areas in selective focus images.
  • 14 elements in 11 groups
  • Minimum Focus Distance 11.02" (28 cm) at 0.21X = 1:4.7
  • Ultrasonic Autofocus Motor
  • Weather-Sealed Design
  • Rounded 9-Blade Diaphragm
  • 72mm filter size
  • Approx Weight 1.67 lb (760 g)

Blue spectrum optics

I’m baffled by “organic” optical materials. The term does not apply to glass, so maybe it really means organic—some new compound.

The violet/blue spectrum is verys hard to control (hence longitudinal chromatic aberration typical present as a violet/purple halo), so this is an interesting development.

MELVILLE, N.Y, August 27, 2015 – Canon U.S.A., Inc., a leader in digital imaging solutions, today announced that its parent company, Canon Inc., has developed Blue Spectrum Refractive (BR), a new optical element for use in camera lenses that corrects chromatic aberrations at an extremely high level to achieve superb imaging performance.

The new Canon-developed BR optical element offers characteristics that significantly refract blue light, which lies within the short-wavelength range, to achieve impressive levels of chromatic aberration correction for outstanding imaging performance. The BR optical element, positioned between two glass lens elements to create a BR lens, will make its debut in the new EF 35mm f/1.4L II USM wide-angle fixed-focal-length lens, which is scheduled to go on sale in October 2015.

Natural light, or white light, comprises a spectrum of wavelengths, or colors, each of which realizes a unique refractive index when passing through a lens. As all colors do not converge on the same point, this disparity causes chromatic aberrations, or color fringing, to occur in an image.

Canon develops optical elements by reviewing organic optical materials, beginning with the design of molecular structures, with the aim of achieving optimal chromatic aberration correction that suppresses color fringing. With the successful development of the BR optical element, which offers unique light-dispersion characteristics that significantly refract blue light—a wavelength that, until now, had proven particularly difficult to converge to a specific focal point—Canon is able to develop lenses that result in outstanding imaging performance by correcting chromatic aberrations at an exceptionally high level.

Press release

CANON U.S.A. INTRODUCES NEW CANON EF 35MM F/1.4L II USM LENS

New L-Series Lens is First to Feature Canon’s Proprietary Blue Spectrum Refractive Optics –
 That Achieves a Higher Level of Chromatic Aberration Correction For Superb Image Quality

 
MELVILLE, N.Y., August 27, 2015 – Canon U.S.A., a leader in digital imaging solutions, today introduced the new EF 35mm f/1.4L II USM lens for EOS system cameras – a wide-angle fixed-focal-length Canon EF lens that is the world’s first* to utilize the Company’s newly-developed and exclusive Blue Spectrum Refractive Optics (BR Optics). This new optical technology utilizes organic material newly developed by Canon to achieve a higher level of chromatic aberration correction than other existing technologies resulting in outstanding high-quality imaging performance.

“As the world leader in production of interchangeable lenses, having produced over 110 million EF lenses since 1987, it is with great excitement that we now introduce a revolutionary new technology to add to Canon’s unequaled optical heritage when it comes to chromatic aberration correction,” said Yuichi Ishizuka, president and COO of Canon U.S.A., Inc. “We continually strive to achieve the ideal lens performance, which has driven the development of Blue Spectrum Refractive Optics, found in the new EF 35mm f/1.4L II USM lens. This technology is yet another ‘first’ in optical design introduced by Canon to enhance the performance of our lenses for our customers.” 

Canon’s proprietary Blue Spectrum Refractive Optics (BR Optics) incorporate a new organic optical material with unique anomalous dispersion characteristics for use in camera lenses. The molecular design of BR Optics refracts blue light (short wavelength spectrum) to a greater degree than other existing optical technologies including UD glass, Super UD glass and Fluorite, to control color fringing as effectively as possible. When placed between convex and concave lens elements made from conventional optical glass materials, BR Optics help to produce sharp images with outstanding contrast and color fidelity by thoroughly reducing axial chromatic aberration.

In addition to BR Optics, the new lens incorporates two aspherical elements and one UD glass element in a 14 element, 11 group optical formula. The EF 35mm f/1.4L II USM lens also features Canon’s proprietary Sub-Wavelength Structure Coating (SWC), applied to the rear surface of the first and second aspheric lens elements to help combat flare and ghosting caused by light rays entering the lens at a large angle of incidence. The lens also offers best in class minimum focusing distance at 0.28m (approximately 11 inches) resulting in an increased maximum magnification of 0.21x - ideal for capturing close-up subjects. Autofocusing is swift and virtually silent due to a rear-focus optical system and Canon’s original Ring USM focusing motor. Full-time mechanical manual focusing is also available even when the lens is set to AF mode.  

The Canon EF 35mm f/1.4L II USM lens features improved durability over its predecessor. As with all
L-series lenses, this new lens is highly resistant to dust and water ─ making it ideal for outdoor photography, even in harsh conditions. The high-grade design of the lens provides users with a substantial and luxurious feel, as well as optimal operability.  In addition, a fluorine coating on the front and rear lens surfaces helps to repel liquids and dust particles, and makes the lens easier to clean.

Pricing and Availability
The new Canon EF 35mm f/1.4L II USM lens is compatible with 72mm filters and will be supplied with Lens Hood EW-77B and Lens Pouch LP1219. It is scheduled to be available in October 2015, for an estimated retail price of $1,799.00.

Canon EOS M3: Coming to USA

The EOS M3 was previously available in Europe and Asia. Now it’s headed for the USA.

The EOS-M I tried back in July 2013 felt unbalanced and uncomfortable in my hands. I can’t say if the same holds true for this new model, but having to mount an EVF in the hot shoe has some pluses, but mainly makes it bulkier.

The EVF-DC1 Electronic Viewfinder works on the EOS M3, so there is an EVF option.

Not using an EVF is a guarantee for increased blur caused by holding the camera at arm’s length. And for me, I cannot see the rear LCD in dim light (unable to focus closely enough). So the camera is really about $920 with EVF in practical terms—still very reasonable but I’m thinking more along the lines of the Sony RX100 Mark IV with built-in EVF and flash, which I consider ideal for portraits in the like in less than optimal lighting (fill flash). And how would one use an EVF and a flash without making things even more complicated (if it is even possible). System cameras are nice, but so it all-in-one convenience.

What I hope is that this continuing effort at mirrorless by Canon (albeit APS-C and way behind the 'curve') sets the stage for a full frame solution, preferably one that takes EF lenses to start, then another that takes a new lens line. But with an EVF, built-in.

No 4K video, no in-body image stabilization, APS-C sensor—well the price is very reasonable, but how does it handle in the hands? TBD.

  • DIGIC 6 Image Processor
  • 3.0" 1,040k-Dot Touchscreen Tilting LCD

Get Sony A7R II at B&H Photo.

I’ve previously written about the Sony ARW raw format, which uses 11+7 bit lossy compression (data is thrown away). This format works very well on 'average' images, but issues show up when the algorithmic premises are violated. Night shots or anything with very high edge contrast are problematic, and the gapping with low values can create posterization.

I want a raw file format from Sony a la Nikon: no data thrown away: a lossless-compressed format. The fine sensor in the Sony A7R II deserves no less.

The images below from RawDigger (more on that below) show the way the raw file is sampled and encoded by the Sony 11+7 bit raw format. It is visually suggestive of issues that might occur in special situations.

DEAL: MacBook Pro

This is essentially a newer version of the model I have used for 20 months as a workhorse in the field (2013 MacBook Pro Retina). I still use it daily as a 2nd machine for some grunt work.

Very approachable price for a solid machine:

Apple 15.4" MacBook Pro Retina (Mid 2014) 2.5 GHz / 16GB / 512GB for ONLY $1749

There is also the 2.8 GHz / 16GB / 1TB model at $600 off.

Or you can go whole hog with the 2015 MacBook Pro Retina 2.8 GHz / 16GB / 1TB model, but the gains are mixed, as shown in my review of the 2015 MacBook Pro Retina.

Service Matters: Leica Q, and a Sony Note

Get Leica Q at B&H Photo.

I’ve previously posted various reader comments on Sony service and support because in my view service and support comprise a good chunk of the product.

Here is one experience from a reader with Leica service. I’ll say up front that my experience with Leica service has been generally excellent, albeit painfully slow at times (up to 2 months). And not always fixing the issue (case in point my 50/2 APO).

John M writes:

I will make a special effort in what follows to present only facts and not my interpretation.

My Leica Q has experienced several freeze episodes where the screen would turn white with a colored noise, as in the attached snapshot. The camera also has the loose LCD screen defect that many people have reported.

On the Facebook "Leica Q User Group" there were reports of the loose LCD screen being repaired quickly under warranty. My contact at Leica USA wrote to me the following:

I have consulted the technician that would repair your camera and he states that he can have the camera serviced for you in the time that you have requested.

I handed the camera to the dealer on August 10th. The expected return time to the dealership was August 31 or before. I had attempted to purchase another Q to use in the interim but Roxana was unable to offer me this option due to lack of stock.'

August 25th I receive the following paperwork from the dealer:

TECHNICAL INQUIRY: LCD IS LOOSE & CLICKS WHEN PRESSED UPON; SCREEN GOES WHITE WITH COLORED NOISE INTERMITTENTLY; THERE IS SOME TYPE OF RESIDUE ON THE CAMERA & IN THE LENS HOOD

SIGNS OF IMPROPER HANDLING
FORWARDING TO GERMANY FOR REPAIR
PENDING ESTIMATE

I called my contact at Leica to ask about this. She stated that the technician will not return until the 27th and she could not explain the issues with residue or improper handling until speaking with him.

I called Dan Tamarkin, my dealer, who stated that it seemed as if something may have been spilled on the camera. I know that this is not the case, although there was an accumulation within the lens hood from normal walk-around use (in those scenarios I use a protective filter). Perhaps a dab of some kind of sticky sauce such as ketchup was on the hood from a close encounter with a child... I seem to have some memory of such an incident. Dan thought that information might end up being pertinent.

Dan also mentioned residue on the body. This was from tape that I had temporarily applied to the body. Dan was concerned that if I wanted the camera back without repairs being completed then we should let Leica know right away so that it would not be sent to Germany. I informed Dan that Leica had already told me (via phone) that "it probably won't go out until next week anyway." This is in the context of a customer who is so desperate for timely service that he is willing to buy a second camera.

Also on August 25th (i.e. a few minutes ago) I told Leica to ship the camera back to Dan, hopefully overnight, so that I can pick up my camera from Tamarkin and continue to use it. The elapsed week and a half is already enough opportunity cost for me, considering that no other Qs are available.

I will be left with a camera that has the same issues, a week and a half of lost time, and a new database record with Leica that my manufacturing issues may not be covered under warranty due to "improper handling."

I should add that my experience is more notable when compared with Sony:

1- I ruined the LCD of an RX1r and told Sony so, humbly asking for a repair estimate... they fixed it for free in less than two weeks
2- I bought a "US version" A7s that ended up being a grey-market import... called Sony and they said they would honor the warranty anyway

DIGLLOYD: it’s disturbing to see the user implicated in “mishandling” without the matter being more rigorously investigated (and discussed). Water damage is one thing (not the case here but speaking generally), but are we supposed to keep our cameras rigorously clean on the outside also?

As a side note, I almost never shoot with only one camera. At the least I have my primary camera and a second one, typically of another brand. For example, in my Mt Dana ascent, I carried both the Leica Q and the Ricoh GR. The Leica Q AF cross-coupling bug threw me for a loop. Though I was able to use manual focus, it impaired my usage of the camera and I was very glad to have the Ricoh GR along. Were I traveling to a special destination (Antarctica, Africa, Icelend, etc) there is no way that I would rely on just one camera body—too much invested in the trip itself to not have a backup. But as John M points out, availability was the issue, not cost.

Image presented dark, as this was how the eye perceived it.

My favorite card: Lexar 2000X 64GB

Lexar Professional 64GB 2000X SDXC
with supplied card reader

B&H Photo has the Lexar 64GB SDXC card with card reader now for only $84.99. This rockin' fast card is now my favorite and the card in that card reader hits about 300MB/sec! Great for big downloads at the end of a long day and far faster than using a built-in SD slot on a MacBook Pro.

In the past I trended to using CompactFlash, but that standard has lagged in both speed and capacity. See also:

Even though it’s not the fastest card, I also like the Lexar 1000X 256GB SDXC for a simple reason: I can make a backup of all critical data and stick it into my wallet and not even notice it being there. Very cool. Get a 2-pack of Lexar 1000X 256GB cards for $275 (as this was written).

I hugely prefer high-capacity cards (64GB or larger) because in the field there is no need to erase them, thus they are an additional backup over and above downloading the day’s shoot (and backing that up too). Aside from cost, I’d be buying 128GB or larger cards for that reason, but for now 64GB serves me amply for most of my trips (not filling up).

Sony In-Body-Image-Stabilization (IBIS) aka SteadyShot: Is There a Downside?

Get Sony A7R II and Zeiss Batis B&H Photo.

I have this nagging feeling, based on field images, that IBIS (SteadyShot) might damage image sharpness, particular when the user is a bit wobbly in odd vectors (me, standing on a 30° slope with the wind blowing). I say this based on a few hundred images I took handheld (see Dana Glacier hike) which for some images have these weird blur characteristics that I am simply baffled by and unable to explain. And these blurs are not typical motion blur; they are varying asymmetric blurs and even look like rotational blur at times. Sometimes not there, sometimes subtle, but my eye has been trained by a few hundred K digital images over years. So I pay attention to pattern recognition by my noggin.

Then too is this idea: with IBIS = off, what guarantees plane parallelism of the sensor? Of course there has to be a lockdown mechanism, but just how accurate and precise is it? The “5 axis” IBIS feature moves the sensor freely, so how exactly is the sensor locked down to plane parallelism to within a micron or so? Perhaps it has more variance might be hoped? I ask this question in part because of the Sony 35mm f/1.4 Distagon skew.

Another question: if a lens is adapted (via lens adapter) to the A7R II (“dumb” adapter), what are the behavioral differences with that non-native lens versus a native (non-OSS) lens with IBIS, and a native lens with IBIS disabled?

I don’t have the answers for these questions, at least not yet. I’m hoping that Sony can fill me in what the behaviors ought to be.

The SteadyShot feature is described by Sony as follows:

The new flagship a7R II model is equipped with an innovative 5-axis image stabilization system that has been fine-tuned to support its high-resolution shooting capacity.

Similar to the system launched on the acclaimed a7 II model, this advanced form of image stabilization corrects camera shake along five axes during shooting, including angular shake (pitch and yaw) that tends to occur with a telephoto lens, shift shake (X and Y axes) which becomes noticeable as magnification increases, and rotational shake (roll) that often affects video recording. This camera shake compensation system is equivalent to shooting at a shutter speed approximately 4.5 steps faster.

Additionally, the 5-axis stabilization works cooperatively with Sony alpha lenses with optical SteadyShot™ (OSS) to provide maximum stabilization and clarity, while also performing admirably via a compatible mount adapter with Sony alpha A-mount lenses without on-board stabilization. Effects of the stabilization can be previewed via live-view on the LCD or OLED viewfinder of the camera.

Thorsten K writes:

You worry about sensor to mount parallelism with IBIS off.

No idea here, but a follow up question: I guess with IBIS being ON, the sensor would not be parallel by design, then? Since IBIS may tilt the sensor to counter-act the user moving the camera? Then for landscapes, IQ would be degraded by design when using IBIS (focal plane would be unpredictable). Or am I missing something?

DIGLLOYD: see notes from Matt G below, which are correct: the sensor is always plane-parallel to the lens flange. However, pitch and yaw are compensated for by moving the sensor in a way that is supposed to optimize the image, and this approximation can cause errors in some areas of the image while improving others. This I take as explaining the confusing sharpness results with the 25mm f/2 Distagon in the Dana Glacier examples. It also explains why my Zeiss Batis 25mm f/2 Distagon tripod-based shots with IBIS off look terrific—no funny business going on with the sensor planarity since no sensor movement.

As per my contact at Sony:

Moving the imager to create pitch/yaw compensation would take the sensor out of perpendicular alignment with the lens. Pitch and Yaw compensation are approximated by X/Y translation – I believe the same as other 5-axis sensor shift systems.

The only system of which I’m aware that can apply mechanical pitch and yaw compensation are those in which the lens and sensor move together as a locked system – Sony uses this in Balanced Optical Steadyshot, included in some fixed-lens camcorders.

Matt G writes:

You ask what guarantees plane parallelism of the sensor with IBIS off. The answer is that it is guaranteed mechanically - the sensor only ever moves in one plane, regardless of the motion being compensated for. This is a source of much confusion since camera marketing materials often suggest the opposite (the Olympus 5-axis system is exactly the same as the Sony one in this regard, despite Olympus publishing diagrams that appear to show the sensor tilting!)

The facts are that tilting the sensor would not successfully compensate for pitch or yaw, and would only serve to throw large parts of the image out of focus. You would have to tilt the lens and sensor together for this to work, but this would require lenses capable of tilting, and huge motors to make it work!

Mathematically speaking, pitch and yaw movements give rise to a projective transformation of the image (the sort of transform you get in Photoshop when using the "free transform" tool and moving the corners of the image). This transformation can be approximated by translation (moving the image up/down left/right), but the approximation is only valid for one location on the image plane, and the error increases with distance from this point.

You can demonstrate the problem easily using a tilt-shift lens. Set the camera up on a tripod with the lens unshifted, lining the centre focus point up with a strong image detail. Take a photo. Pan the camera on the tripod slightly, inducing a yaw movement. Next shift the lens so that the same image detail is again exactly under the central focus point. Take another photo. When you switch between the images the centre will look roughly the same, but the corners will appear to change shape.

This effect is what is causing the asymmetric blurs you are experiencing.

The problem is not with the Sony implementation, IBIS is not a substitute for preventing camera motion in the first place, and I would not use it for landscapes or still life images where the corners of the image will be in focus.

DIGLLOYD: well, I guess I don’t understand what “5 axis” means then. I can understand translation (left/right, up/down) and rotation, but that’s 2 directions plus angular for a total of three. But if pitch and yaw are compensated for by those movements by moving the sensor to some “intersection point”, then it seems that the cure is worse than the disease and I’d like a setting to disable pitch and yaw correction. I’d rather have traditional motion blur than some unpredictable asymmetric weirdness.

Matt G follows on to the above:

In response to your updated blog post, disabling pitch/yaw correction would be fairly pointless. Around 90% of camera shake (depending on focal length) is due to pitch and yaw. You might as well disable the entire system (which is something I would recommend).

Camera translation (up/down, left/right movement) has very little impact on the image (in general). If you put a telephoto lens on a tripod look at a distant subject and then drop the centre column by 1cm, the image in the viewfinder will hardly change at all. Pan the camera slightly and there will be a huge shift in the image. Translation only has a noticeable effect at high magnifications.

The second point in favour of pitch and yaw correction is that the longer the focal length, the closer the real projective transformation gets to a affine transformation that is readily approximated by translating and rotating the image. A simple way to visualise this is to again mount a telephoto lens and pan the camera left and right and the image seems to simply shift left and right. Now mount an ultrawide lens and do the same, the corners appear to stretch and warp in a complex way.

This is true of both optical and sensor-shift stabilisation systems, and explains why image stablilisation first appeared in telephoto lenses and is rare in wides.

IBIS ought to work fine with no artifacts for normal to long lenses (for small movements, otherwise you run out of sensor travel and image circle). But for something like the 25mm Batis I would only use it for shallow DOF shots where the corners are out of focus.

DIGLLOYD: I’m going to disable IBIS for wides in unstable situations or a lot of near/far detail, but use it for f/2 and f/2.8 for dusk shooting or similar. My tests show that at 1/20 sec, IBIS helps. I am dubious about 1/60 on up, where I think I can do better without it.

A major selling point for some uses is In Body Image Stabilization (IBIS) aka Sony SteadyShot, because image stabilization is brought to every lens mounted on the camera. CaNikon cannot do such a wondrous thing.

I wished to know for my handheld shooting what my odds are with IBIS. And so I evaluated Sony Steady Shot (In Body Image Stabilization aka IBIS) at 1/20 sec handheld using the Zeiss Batis 25mm f/2 Distagon.

IBIS (In Body Image Stabilization) Handheld at 25mm

I used my best technique as described in How to Hold a Camera Steady (Mass Coupling). Tested in 4 variations all handheld, 10 shots each (40 shots total, all shown):

  • IBIS enabled, single shot exposure.
  • IBIS disabled, single shot exposure.
  • IBIS enabled, 2 second self timer.
  • IBIS disabled, 2 second self timer.

The points of interest are:

  • Is 1/20 second realistic for a 25mm lens?
  • How much does IBIS help, and is it consistent?
  • Does IBIS function with the 2-second self timer?
  • Does use of the 2-second self timer help in obtaining sharp shots? (by avoiding the disturbance of pressing the shutter release).

Deal on Big Storage for Photographers: OWC Thunderbay 4 RAID-5 Edition with Extra 4TB Drive

OWC has the the OWC Thunderbay 4 with free spare 4TB HDD in tray on special this weekend for $1149 (about $350 off).

It’s the RAID-5 edition with an extra (cold spare) drive. That’s five 4TB hard drives total. Use the cold spare as a backup in the meantime—no need to let it sit in drawer (hint: buy a 2nd empty Thunderbay).

RAID-5 is fault-tolerant meaning it can survive the failure of one of the drives: swap it for the spare and keep working.

You can run the unit as a single 12TB RAID-5 volume, or (my preferred approach) partition it into three separate 4TB RAID-5 volumes. Or not use RAID at all, and use the drives as single non-RAID drives.

See the MPG review of the OWC Thunderbay 4. I have FIVE of these units—favorite storage device ever.

UPDATE: OWC also has the 5.0TB Toshiba drives with 3 year warranty for $163.99. Perfect for the Thunderbay, and OWC’s 90-day DOA replacement guarantee* beats anyone out there that I know of.

* If a new drive fails within 90 days OWC will replace it with a new one.

Sony A7R II: Focus Accuracy Better than Any DSLR I’ve Ever Used

Get Sony A7R II and Zeiss Batis B&H Photo.

See my in-depth review of the Sony A7R II.

Something strange happened on my recent trip: I did not see any mis-focused images from the Sony A7R II. I mean, none.

Try doing that with a Nikon D810 or Canon 5DS R with an autofocus lens—I have and never come close, as past autofocus assessments show. And it’s hopeless to focus a lens manually using the optical viewfinder in a DSLR—the focusing screen is designed for autofocus and can’t show more than about f/2.8 - f/4 equivalent—massive slop—and it is a different optical path almost never the same distance as the sensor (inherent error even with perfect eyes). So one has to resort to magnified Live View using a loupe—clumsy at best compared to an EVF, though it’s perfectly reasonable on a tripod. The omission of an EVF option with the Nikon D810 and Canon 5DS R is so at odds with usage realities that it begs credulity.

Some advances really matter: those that eliminate or greatly mitigate longstanding technical challenges that reduce the hit rate.

Add the electronic first curtain shutter for zero vibration: focus nailed every time, plus no mirror slap, all handheld. And image stabilization to boot no matter which lens is used (and just about any full-frame lens of any brand can be used, with adapter).

The DSLR is looking like not just a dinosaur, but a lame dinosaur, given these advances. How long will CaNikon watch Sony advance without responding? The optical viewfinder is great for some things, but I say get rid of it—it is a huge liability for most things. Mirrorless is now the leading technology on the market, solving real issues for real photography.

The Sony A7R II makes outstanding images with low noise and excellent dynamic range at 42 megapixels that are always in focus. Notwithstanding some file quality limitations and disappointing 12-bit behavior in certain situations, nothing else can touch this track record of ultra-high hit rate. And it does so in a relatively compact form factor: when I shot the Dana Glacier examples, it was the ideal camera; I could not take a tripod climbing class 4 and class 5.0A, so the Nikon D810 was really a non-starter there (at least without more planning and difficulty). And so I would say this: I think it is a mistake to 'diss' the Sony A7R for its faults, which most of the time either have a workaround (very careful exposure) and/or are unusual or rare. Trade that off against focus errors of all kinds, size and weight, etc. It’s a fair trade. When and if Sony can fix the few image quality issues, and perhaps add a bit more dynamic range with a Nikon D810 style ISO 64, it’s going to be very hard to argue in favor of any DSLR for 99% of shooters, including my workhorse Nikon D810.

Sony A7R II: Examples with Zeiss Batis: Dana Lake, Dana Glacier Climb

Get Sony A7R II and Zeiss Batis B&H Photo.

These images are a hiking documentary series of the upper Dana Glacier Canyon and Dana Glacier, in the Ansel Adams Wilderness abutting Yosemite National Park. It is a strenuous hike to get to the glacier over multiple extended boulder fields involving class 4 climbing and a brief section of class 5.0a and an 'interesting' down-climb of the latter.

Thus the A7R II and two Zeiss Batis lenses were employed in an ideal real-world scenario that dovetails with the strongest core features of the A7R II: relatively small and lightweight lenses, full frame sensor, image stabilization, the convenience of an EVF. Shot without a tripod, as climbing in such conditions is a risk with a tripod.

Includes ACR conversion settings analysis for each image, notes on the scenery, and images up to 24 megapixels, some with crops.

These examples offer a wide range of images and conversion options showing the excellent image quality of the Sony A7R II under most circumstances, and are an excellent juxtaposition against difficult scenes that are not the rule.

Stunningly beautiful images! Period. Full Stop.

I especially liked the inclusion of BWs having spent many nights in the darkroom with my Pentax 6.x7 Tri-X Professional negatives working on the Zone System.

DIGLLOYD: I was so excited to get up there—physically strenuous but what a raw wild place. I hope it comes through in the images. My only regret is not spending time till dusk there, because it is a long descent with big boulder fields and such. Sometime I’ll camp there and enjoy sunrise and sunset, perhaps in late October.

As for B&W, I’m decent at conversions, but the bottom line is that a high-res RGB image blows away any monochrome technology, because it allows mapping colors to grayscale relationships in an infinite number of ways—post shot. It is why I no longer have any desire for a monochrome camera (unless it were, say, 70 megapixels on up with an ISO 64 setting and 14+ bit dynamic range).

Sony A7R II: Where is Pixel Shift?

Get Sony A7R II at B&H Photo.

Pixel shift is a technology available on the Olympus E-M5 Mark II and on the Pentax K3-II as of today. It moves the sensor in single pixel increments in multiple directions, building up a composite image (in raw format or JPEG). The multiple samples (exposures) increase total exposure time, but reduce noise.

Pixel shift avoids / mitigates the RGGB Bayer matrix limitations, thus providing true color at each pixel and lower noise, and with enough shifts, increased spatial resolution as well. It requires a non-moving subject and camera and can produce ugly artifacts if those conditions are not met.

Though pixel shift is not a panacea and is tripod-only (at present at least), it is an awesome feature that is oddly lacking in the Sony A7R II, which has its IBIS feature (In Body Image Stabilization).

Conspicuously missing from the Sony A7R II feature set is Olympus-style pixel shift, which in my testing can deliver roughly a 32-megapixel image from a 16-megapixel sensor. On the 42-megapixel Sony A7R II sensor, a similar technology could in theory deliver ~80 megapixels (or 42 without Bayer artifacts), although a lens of Zeiss Otus grade will be mandatory.

It’s a pity that Sony is not offering pixel shift. Perhaps it will appear in a firmware update, but that seems dubious, since it is a terrific feature to brag about at a product release (and would be a first for a full frame camera). It might also be a problem to implement with the current Sony 11+7 bit raw file format; it demands a true 14-bit format, if only not to waste the huge bump up in noise reduction in dark tones.

If Sony does not implement pixel shift, then the most likely candidate is the coming Pentax full-frame camera, which utilizes the Sony 42-megapixel sensor (pixel shift already exists in the Pentax K3-II). And then one wonders about Nikon, which at the least ought to offer a Nikon D820 with the new 42MP Sony sensor, though we can hope for more.

Sony A7R II, Sony Lenses: Reader Comments

Comments on recent coverage of my expanding review of the Sony A7R II and related lenses.

Michael writes:

Thank you for being the only one out there for calling it like you see it with the Sony A7RII and the Sony lenses. I am kind of amazed that so many people are not really criticizing this camera for it’s faults and are only lavishing praise upon it. I am sure it is fun to shoot with but there are some very serious issues that you have pointed out.

As a Nikon shooter for many years and a full time pro I have been on the fence about the new Sony offerings and have tested several of the A series cameras. As a sports photographer, I have yet to see one of the A7 series work for my needs, but reading about the decentering issues with Sony lenses you and others have reported on as well as the hampered raw file issues has really curbed a lot of my enthusiasm for these cameras - at least in terms of work.

I want to love them as they have cutting edge features but for my work I need a camera to be reliable all the time every time. Thanks again.

DIGLLOYD: the Sony A7R II body itself has been 100% reliable in operational terms, which is more than I can say for Leica M or Leica S. So some credit is due there.

The only valid metric I can see for lens quality is a sampling on the open market of a statistically valid number of lenses. This I cannot afford in time or money. So I report on what I find, as I figure my odds are the same as those of any other buyer.

There is always some quality variance and I make no claim to the quality statistics. I can only report what I find with what I receive, taking care to rule out the camera body as well as may be. And so far, the 35/1.4 and 90/2.8 have not delivered for me (two samples each). I do have a good 55/1.8 however, as proven on the very demanding mosaic target. I should also note that I do not know if Sony SteadyShot (IBIS) could cause problems on the A7R II: what guarantees plane-parallelism to the sensor, when IBIS is on or off? Could IBIS itself be an issue? I don’t know.

Now in general—

My full camera reviews take time, and I report what I find as I go along. My goal is a balanced view with all the good and bad by the time I finish it. I am disappointed but realistic about the way readers flog one negative or blog post as a single issue that decides all—as if that’s all I had to say about it. Much of what I write is twisted and distorted with dropped context and/or false assumptions (especially by non subscribers who haven’t even read my work). Well, that’s life. Even when I provide balance against a negative, this is misinterpreted. I’m going to keep reporting the way I do—agnostic on brand, merciless to flaws, praising the best, lamenting the mediocre, objective as I can be. Which is to say I am perceived as a hater or fanboy of product X (both wrong), depending on which one is owned by the fan. And to say that I have hit the mark squarely.

Look, here’s how it goes:

Chocolate ice cream is tasty” = “diglloyd hates vanilla and strawberry or chocolate with almonds”.

I have an unbeatable ally: objective reality. A million people claiming the world is flat does not make it so (witness the Sony A7R shutter vibration fiasco). When I make a mistake or an error, I handle that the only way possible: I fix it because there is no other option, not in my world. I can only do my best, which is a much as anyone can do. High States.

I own nearly all these systems and the only thing I wish to see is continual improvement in all of them. That cannot happen by glossing over weak points.

P.S. the above will no doubt be misinterpreted as to motive!

P.P.S: I like the Sony A7R II a lot for its best features, I wish Nikon would make a D820 with the A7R II sensor and EVF, and I wish Ricoh would make a full-frame 42MP Ricoh GR follow-on. And so on.

Sony A7R II: General Commentary

Get Sony A7R II at B&H Photo.

This is a general commentary speaking to the body of my expanding review of the Sony A7R II. But the comments here reference in particular Sony A7R II: Posterization with a Near Optimal Exposure in Daylight (Portrait at Dana Lake).

The A7 system has some very fine attributes (sure is nice to carry and I love having an EVF and IBIS). Operational controls and haptics need improvement (I've commented upon the issues in my review), but those things might not concern many users.

When light or color or dynamic range is unusual, the file quality can become an issue, and this shrinks the operational envelope. The blue lake is not some test scene; it is a real scene of rare and special beauty (I’ve never seen its equal in Yosemite). Experiencing that incredible range of blue (continuously variable too!) in person is stunning. And so I wish to record the special things I see without worrying that the camera will fail to record it properly. So I am adamant that the 11+7 bit file format needs a Nikon-grade 14-bit sibling and that the RGB histogram needs work.

Were I to reshoot, I’d bracket and I would not polarize, but in this case I had wanted sheen off the face, which is why I polarized it. I knew the blue was intense and had I stopped to consider, I’d have known that this could be problematic for the red channel. But I was focused on a series of pictures (many more besides that one).

But here’s one rub: the Sony A7R II offers a coarse histogram unsuitable for discerning issues in small areas of the frame, and it offers no RGB histogram just for the zoomed-in area, so even after taking the shot it’s not possible to be certain of the exposure for critical areas, like the face or water. This is a flaw as one can see just by using a Nikon D810 which does it right. I have also observed misleading errors in the Sony RGB histogram when comparing to the actual raw data in RawDigger. Such things are a handicap for field use, but Sony could fix it. The only quick and practical solution at present is bracketing such scenes, which is not all that viable for facial expressions. Oh, and continuous shooting drops to 12-bit mode so how does one bracket quickly, except frame by frame? (though maybe bracketing is not continuous mode and so is not affected, not sure). The A7R II has various file quality land mines of this sort, which in my view undermines its merit as a professional tool. And yet is is very, very capable in ways that make it a better tool under some circumstances.

Sony could issue a firmware update for a lossless-compressed 14-bit file format as well as fixing some problematic behaviors, like dropping to 12-bit mode with Bulb mode, and long exposure noise reduction mode making things worse in some cases. And Sony could improve the RGB histogram behavior and quality. But the issues may run deeper, e.g., excessive processing of the raw data aka “cooking”. And the electronics might not be capable of quality sufficient for a true 14-bit format. Still, a high-grade file format would be a good start that would make the Sony system more credible as a professional tool (albeit of no interest to many casual or routine shooters, many of whom are probably viewing the blue lake on a display capable of little more than sRGB, if that and/or (hopeless) iOS which doesn’t even support color profiles).

As I've written before, Sony cameras feel like camera imitations, not the real thing (the Leica Q feels like the real thing, as does the Nikon D810 or Canon 5DS R). The Sony camera gestalt seemed to be deeply cultural and it may take a long time, if ever, to overcome some design patterns*. Which gives NiCanon some breathing room, in theory. But Sony has made some serious progress with the A7R II vs the A7R, and I applaud those advances—keep ’em coming. In particular, the Sony A7R shutter vibration that did not exist (my findings were repudiated by Sony) is now fixed in the A7R II (how does one fix a non-problem?)—to my lasting relief I can shoot without having a great deal of work ruined, as was the case with the A7R.

I like the A7R II and I will be buying one. Now I just wish for Sony to improve it via firmware updates. If Sony wants to listen, they can ask me for my wish list*, and that goes for any vendor out there. But no vendor ever asks. Maybe Sony can be the first? My goal for all brands is to see the offerings improved, which is why I spell out everything I find, as I have for years.

* At least eliminate the Applications menu which just annoys by occupying space.

These points may serve as evidence that this next wish isn’t possible in the A7R II:
'Sony could issue a firmware update for a lossless-compressed 14-bit file format'

It’s starting to smell like Sony is/was compensating for bandwidth deficiencies in the A7R II’s implementation. Having done signal-processing type firmware work myself, tricks like dropping to 12-bit mode and the lossy RAW format, all sound like “cutting corners by putting in a bunch more work” that resource constrained firmware systems sometimes have to do.

Certainly the 11+7 bit format is a legacy inheritance now, which might excuse its continued presence if you squint just right. But dropping to 12-bit mode is a curious limitation, which I doubt is capricious.

DIGLLOYD: Agreed. The drop to 12-bit mode could indicate a quality issue within the sensor/electronics pipeline. Sony claims 14-bit files and 14-bit pipeline, which offers hope. But the lossy format can hide some issues. However, 14-bit lossless-compressed file format might also provide a useful noise dithering in dark tones.

In general, the next quality front is surely dynamic range. A camera that delivers a robust 15 bit dynamic range would be highly desirable (though few if any lenses can deliver that). And technology for bit counters on a pixel could make arbitrary dynamic range is possible (4 bit or 8 bit or whatever bits for overflow on each pixel).
