A chat today with Ming Thein of MingThein.com, a professional photographer half way around the world (from me) whose work is excellent and writng is equally solid. He has his own shooting needs, and his The Nikon D810 review: a worthy D800E upgrade? is worth a read.
This chat is a little rough, but it was unscripted and unedited and with chat there is some overlap (out of order) as one person types/responds to a prior.
Perhaps we’ll do more if readers find it enjoyable (update: yes, very positive feedback).
diglloyd: My first thought on the 645Z is lenses.
Ming Thein: Same - or rather the lack of?
diglloyd: or rather lens selection. The lack of more than a few (if that) really good lenses. the 90/2.8 macro is really good, but are there others of that grade?
Ming Thein: The SDMs are the best of the bunch - yes, the 90 is outstanding, the 55 is not bad - much better stopped down, and the 25 gets there by f8.
diglloyd: On the 25...
Ming Thein: I would say it probably matches the Zeiss 2.8/21 by f8. But sample variation is a disaster.
diglloyd: My test showed that it cannot match the Zeiss 21/2.8 at any aperture. But I had one sample and you had four? Seems like probability for a mediocre $5K lens is way, way too high. Compared to Zeiss Otus which holds very tight tolerances in manufacturing.
Ming Thein: And that's the troubling thing. The first sample would not focus to infinity and was clearly astigmatic. The second one was astigmatic. The third was not bad. The final one is pretty good.
diglloyd: I’d expect fairly strong astigmatism in it as a wide in any case.
Ming Thein: At least, the one I purchased matches my 2.8/21. I think we have to remember it's a 19mm-e on 44x33 but covering full 645 though. And that's pretty darn wide, even though it doesn't seem to render as such.
diglloyd: But the thing is, where is the 15/2.8 and 25/2 or 25/2.8 equivalent... no T/S, etc. That’s the rub.
Ming Thein: Or leaf shutter lenses.
diglloyd: True enough though the 645Z it’s 21mm equiv exactly across the long side.
Ming Thein: But in all fairness, Hassy and P1 don't have these either. Hassy has the 1.5x HTS, Phase has one Schneider 120 macro TS, and that's about it. My bad, was thinking diagonal.
diglloyd: Heck I’d like to see leaf shutters on a DSLR.
Ming Thein: You can have it. It's called Leica S.
diglloyd: IMO the very best glass is Leica S.
Ming Thein: And then you can also be broke. Well...I think the Otus gives it a run for its money. At least it will when the lineup is complete - and at f1.4 instead of 2.5, and half the price (or less).
diglloyd: The lenses would be OK (buy used), but the S body is an OMG and way beyond me.
Ming Thein: And that really demonstrates relative value, doesn't it? The 645Z is what, one third the price of an S?
diglloyd: Yes, the Otus is faster by more than a stop even in format equivalent terms. Otus is no less good than S lenses that I can see. Frustrating. Yes, GREAT sensor, and Ricoh has those controls (mostly) nailed. Thoughtful design.
Ming Thein: Personally, it seems MF in general is not really there, for any system.
diglloyd: I’d agree. I’d like to see Leica offer S glass for a variety of MF bodies. backfocal distance a problem with current designs though (precludes adapter at least). But that 645Z sensor is a nice piece of work. But results are sensor/electronics + lenses (plus of course the wetware behind the camera).
Ming Thein: I've tried Hassy V film and digital, Hassy H, Leica S, and now P645. Each has some pretty significant drawbacks - V tops out at 1/500s, has no wides and has to deal with a body designed for square and digital backs that are rectangular. Hassy H feels terrible ergonomically and just operates very clunkily. Leica S is eye wateringly expensive, the sensor lets the whole thing down compared to the competition, and the S2 I used had some serious FW bugs - it wouldn't write anything to card subsequently if you changed ISO whilst it was saving. P645 lacks lenses and leaf shutters, but has the best sensor and ergonomics of the lot. Phase One...well, nobody from them ever replied any of my emails, so I wouldn't know. I'd say customer service is a bit of a disaster in Asia...
diglloyd: Seems like Zeiss is the perfect fit for MF like Pentax 645Z: Otus grade for MF. Tiny market though and is it needed? Who *needs* the 645Z.
Ming Thein: Honestly? Very few people could even really maximize the potential.
diglloyd: Agreed on those systems. BUT... Leica S could conceivably go to 50 or even 80 MP and that would start to look more compelling.
Ming Thein: I personally think the 645Z should really be shot like a DSLR, not a MF camera for best results: because it'll give you MF results where you couldn't even come close before. And THAT is interesting, in my book - both pictorially and technically.
diglloyd: Agreed. 645Z feels like a big Nikon to me.
Ming Thein: There's no 80MP 33x44 sensor - yet. And the 50MP sensor would make it equal to the H5D-50C, IQ250, 645Z etc. - but probably at the same price as the P1 or more. Actually...I prefer the 645Z. Nikon still haven't mastered the art of mirror lockup.
diglloyd: There will be... and S glass should hold up.
Ming Thein: Self timer = auto mirror up. What's so difficult about that?
diglloyd: Ricoh did execute really well. It’s so *obvious* so why do so many vendors do it wrong.
Ming Thein: At 80MP on that sensor size, we're talking ~45-50MP on FX - that's diffraction limited by f5.6-8. I don't know how useful that's going to be practically, to be honest.
diglloyd: But Ricoh screwed up like everyone else on one point: why is there a 30 sec limit on exposure time without jumping through hoops when the sensor can do an hour with aplomb.
Ming Thein: Many things are obvious, but laziness, inertia, and design by consortium seem to be the main causes. Ricoh and the GR are a good example of doing it right - there's really *nothing* to fault about that UI. Put the camera in B or T
diglloyd: I see 80MP in that size as debayering cleanup in large part.
Ming Thein: One press to open, one press to close. But yes, timed multi-minute options would be nice. One stop increments at that point would be fine, too.
diglloyd: B doesn’t cut it: who presses the button? I’m in the cold at 30°F the wind is blowing and I’m gonna **#$848#$ stand around to press a button?
Ming Thein: I suppose there's that wireless card + app. I see that as being useful for landscape work. You DID walk out in the cold 30F wind in the first place... I have a Norwegian student who says there's no such thing as bad weather, just incorrect clothing.
diglloyd: Yeah you can always carry extra crap along... that’s what I’m forced to do with the Nikon.. carry an MC-36 whose battery is always low.! Give that Norwegian student 30 more years and a pot gut and we’ll see.
Ming Thein: Speaking of batteries, I'm finding my Nikons seems to be self-discharging of late - all of them. New batteries especially. I wonder what's up with that - down 10% or more after letting them sit for a week. He's 60.
diglloyd: Point is, so EASY to just allow user to select 60 or 90 or whatever: Ricoh GR goes to 5 minutes piece of cake built in.
Ming Thein: And with an ND filter, but that's another thing altogether.
diglloyd: all right, give him 30 more years! :;
Ming Thein: He'll be dead (probably) Speaking of ND filters, the 25mm is a bit of a disaster: ultra thin drop in NDs are required in an odd size - good luck finding them. I haven't been able to.
diglloyd: The lens is supplied with one, isn’t it?
Ming Thein: CPOL.
diglloyd: Well, then you have a 1.5 stop ND that cuts glare huh.
Ming Thein: But sometimes you want a bit of reflection.
diglloyd: Odd that no screw on front. Zeiss can do a 15/2.8 with screw-in front, so it’s a design thing that need not have been done that way. Absolute... “dead” things creepy if too much POL.
Ming Thein: I admit I'm mostly just being difficult because I've never used an ND much before on wides, but I could see experiments I'd like to try - especially with 1h exposures.
diglloyd: Did this piece and many others... definitely do not want too much polarizer off. diglloyd.com/blog/2014/20140120_1-polarizer-choices.html
Ming Thein: Agreed.
diglloyd: Haven’t tried but does the 645Z have a (non) ISO 50?
Ming Thein: No, 100 is the lowest. Let me double check.
diglloyd: I do like ISO 64 on the D810. Very impressive quality. ISO 31 (non ISO) is soft though, not appealing.
Ming Thein: Yes. 100 is the lowest. Is 64 better than 100 on the D800E?
diglloyd: I keep wondering if Nikon went to a mirrorless design accepting current F lenses and made a 36 X 32 sensor... many lenses would work quite well I bet. Otus 55/1.4 would.
Ming Thein: Trouble is, other than for long exposure work or video or extremely fast lenses and tropical noon, I can't imagine wanting less shutter speed - especially given more shutter speed = less shake...
diglloyd: YES, 64 is definitely better. Not that 100 is bad, but the first inklings of noise show up at 100.
Ming Thein: Are we talking the D810 or the D800E here?
diglloyd: ISO study of D810: https://diglloyd.com/blog/2014/20140720_2318-NikonD810-noiseISO-fruit.html
Ming Thein: 30x30 square!
diglloyd: Along with chroma noise reduction: https://diglloyd.com/blog/2014/20140723_0900-NikonD810-noiseISOChroma-fruit.html Yes, that too. Or maybe 32 X 32 to push it. D810
Ming Thein: Would you say it's a noticeable step up over the D800E? As in: given what you're likely going to lose selling a D800E, and have to pay to upgrade...
diglloyd: Well, D810 high ISO superb too up to 3200 or so, and one must keep in mind reproduction size which relates to number of pixels. Yes, D810 step up... both operationally already saving me time and image quality a notch higher too. Hard to quantify though.
Ming Thein: If you keep doing this I'm going to send you a bill later.
diglloyd: I’m gonna sell my D800E and buy the D810.
Ming Thein: The thought of doing the mirror realignment dance doesn't excite me though.
diglloyd: Tear the mirror out and use LV only with that EVF non option?
Ming Thein: I've spent so long making manual focus usable on my D800E pair that I am really loathe to sell and do it again.
diglloyd: It’s time to lose the mirror as one option.
Ming Thein: I'd go for that. But I don't know if Nikon has the balls, frankly.
diglloyd: Don’t sell it then. D800E remains a strong camera. My needs involve precision so I have to have the best Live View and no vibration electronic shutter and so on. Not the same as street. Nikon is female. The quiet shutter is a big plus on the D810.
Ming Thein: Well, most of what I shoot commercially is stopped down on a tripod with controlled lights. The street-urban type work is mainly for teaching and personal entertainment.
diglloyd: then you want a D810 for its operational behavior in LV.
Ming Thein: Mirror/ shutter vibration was and is a big deal on the D800E. Does the D810's mirror buy you any extra handholdability?
diglloyd: Massively better Live View on D810: https://diglloyd.com/blog/2014/20140719_2030-NikonD810-LiveView.html
Ming Thein: I must be the only person who's never had an issue with the D800E's LV. I honestly view the mirror as a much bigger impediment to IQ
diglloyd: Well, see my actual photos of both. D800E = hideous mangled blurred view. D810 = clear.
Ming Thein: That's significantly better.
diglloyd: Mirror handheld shooting? Cause on a tripod not involved with MLU.
Ming Thein: It's a wonder I could make sharp photos at all with LV!
diglloyd: Have a drink or two first for tharp pictures.
Ming Thein: No, the mirror mechanism - Nikon claimed less vibration, which should theoretically improve handholdability. Tripod is academic.
diglloyd: Have not evaluated that... but the D810 seems nicely quiet.
Ming Thein: I'm finding 1/125s is the borderline for consistently sharp hand-holding with the Otus, but my hands aren't that steady.
diglloyd: Maybe that quietness is the mirror damping you refer to.
Ming Thein: Yes and no. Cameras like the F6 have a loud mirror but surprisingly good damping.
diglloyd: I can shoot down to 1/15 and with 3 or 4 frames get one tack sharp. I call it mass coupling: https://diglloyd.com/idx-msi.html#LiveView
Ming Thein: Others have a loud mirror and poor damping (Sony A850, for instance) 1/15 is on a tripod or handheld + LV?
diglloyd: Agreed... but one expects some correlation with similar era design.
Ming Thein: I think if one used an LCD magnifier + LV you could probably get much lower than with the finder.
diglloyd: handheld: couple the camera to the slow-moving body.
Ming Thein: Actually, I think the correlation is all cost related... The F6 was/ is expensive. And has no digital bit, either. So all that cost has to go somewhere...and I doubt it's margin, given the lowish volume.
diglloyd: possibly, but it’s all about eliminating high frequency vibes... and mass coupling (holding technique) can do that. It can’t damp the mirror I suppose. Some canon bodies better that way I think. Makes sense. Mass market era even at $3K.
Ming Thein: Talking about high frequency - to me, that remains a problem with mirrorless: all of them still have this shutter shock problem.
diglloyd: and half of cost is electronics so physical stuff gets shorted.
Ming Thein: Precisely. EFC solves it to some extent, but introduces other compromises like rolling shutter artefacts or no drive modes.
diglloyd: Sony A7 in EFC mode has no shutter shock. Nor Sigma Merrills, etc. leaf shutters (all). But you know that.
Ming Thein: Sigmas use a leaf shutter. The A7 would still have rolling shutter issues, no?
diglloyd: Yeah but Sony A7 does not and can be shot all the time in EFC mode. Rolling shutter issues for still frames? That’s a real concern?
Ming Thein: At high shutter speeds/ fast moving objects, yes
diglloyd: Sure... one can pop out to regular mode I suppose. But dusk in an alley....
Ming Thein: I can think of several situations in which I'd have had very strange results from a sequential readout shutter Also true Question is why didn't they put that EFC mode into the A7R, which needs it more...
diglloyd: Better to have option than not and hard vibrations (Sony A7R). CPU speed? or sensor limitation?
Ming Thein: The A7R has other issues, like data compression. And again lack of lenses.
diglloyd: Leica M has same problem as A7R, only somewhat less severe. Ruined all my long tele shots in the field. But that might change soon. 😊
Ming Thein: I wouldn't use an M for tele work. The EVF is silly, the RF useless above about 75mm, and that leaves you on a tripod. It seems that body hardware is progressing much faster than lens choices though. Lots of new systems, only M4/3 and Fuji seem to have fleshed everything out so far.
diglloyd: EVF is immensely useful to me on M (focus accuracy).
Ming Thein: True - but why bother with an RF at all then? You might as well use a D610 and live view. Or an A7/7R.
diglloyd: Back to D810: I see it as a workhorse. It’s not great by any means (so many “could have done this right”), but it is a true workhorse. Because red dot stickers are cheap.
Ming Thein: Isn't that pretty much true of most pro Nikons? I seem to always come back to one for serious work
diglloyd: M lenses are kinda nice at times.
Ming Thein: Because all of the system bits are there, and they get the job done. But I find them very difficult cameras to love
diglloyd: Kudos to Nikon for making something solid.
Ming Thein: It's only the Zeisses that give them some magic
diglloyd: Nikon makes too many easy things too hard. like it has always been. But need not be.
Ming Thein: Out of curiosity, is there any Nikon glass you like at all?
diglloyd: That’s a good point: today’s lab test for lenses are just a spreading malaise. Nikon glass... yes...
Ming Thein: A lot of photographers have forgotten how to use their eyeballs and brains.
diglloyd: Points to the 14-24 for an incredible zoom for when you need it (focus shift sucks at close range though).
Ming Thein: I actually don
diglloyd: eyeballs applied to web page charts. :;
Ming Thein: don't like the corners on that thing. And yes, I've used three of them, too.
diglloyd: Corners are good on 14-24. It has differential focus shift. https://diglloyd.com/idx-msi.html#CaseStudiesFocusShift
Ming Thein: And some field curvature and CA too
diglloyd: Took me 2 years to figure out the friggin’ 14-24 behavior. See my differential focus shift case studies. It will clear up a lot. But... not that much I care to shoot on Nikon: not much magic.
Ming Thein: I find it easier and cheaper to mount my 21...
diglloyd: (Nikon lenses). Some very good, none great.
Ming Thein: I'm inclined to agree. I tested a 200/2 VRII recently - one was going second hand at my usual dealer - and was a little disappointed, especially compared to the 2/135 APO.
diglloyd: Well, the 14-24 has very low distortion in the 21-24mm range. Zeiss 21/2.8 I prefer also, but has wave distortion... all depends on subject I guess.
Ming Thein: That's what ACR profiles are for.
diglloyd: 200/2 is way overrated on sharpness. Good in central 1/2, then doggin’ it and f/5.6 - f/8 required. ACR can help but that micro contrast gets whacked by correcting. And that’s part of the Zeiss magic. Well, D810 sensor I’m not so sure is ideal yet.
Ming Thein: Oh? Personally, what I'm increasingly finding is that I'm matching one or two lenses to a body/ system and working that way - it seems necessary to get the best across the board. There's no longer a one-size-fits-all system as the pixel counts keep climbing.
diglloyd: Sensor cover glass non optimal.
Ming Thein: Interesting. What's the giveaway? Flare?
diglloyd: That works. I had to have my D800E bodies gone over special 2 years ago to get the sensor/mount aligned.
Ming Thein: And that's one of the reasons I'm loathe to get an 810 - QC seems so bad these days that I really don't want to go through that again. But maybe that's a working pro's standpoint: it works, it's reliable, clients are happy - why spend more to change?
diglloyd: Not flare... just less than peak sharpness that ought to be there. Otus is designed to all but eliminate it, but many lenses seem less good than I’d expected (e.g. older Nikkors). B&H Photo: 30 day returns. 😊bh_nikon But easier here in USA.
Ming Thein: Older Nikkors just don't seem that good to me in general. Even my 58/1.2 NOCT really needs f2-2.8, and even then, it isn't even close to the Otus. It is smaller and cheaper though, I guess.
diglloyd: Yeah that’s part of it—just not that great. But I think some of the Zeiss wides are impaired slightly. NOCT need f/5.6! Had a cherry picked one... order of magnitude under Otus. But ‘style’ lens of course.
Ming Thein: I wonder if this pairing thing is just something we're going to have to get used to. GR for wide, D800E + Otus for the midrange or P645Z and 55/2.8, then back to Nikon again for anything over the 90
diglloyd: MF suffers badly in that regard.
Ming Thein: I bought it as an investment to go with my F2 Titan.
diglloyd: Keep it. I wish I had mine. Sharpness is not everything.
Ming Thein: That's the plan. I shoot that combination for fun and to decompress.
diglloyd: The Nikon 28/1.4 is not all that great either, but I loved the way it draws. Sold that too. Darn.
Ming Thein: And to remind me what a real camera should feel like. I actually came across a couple of those recently - I really don't like it, surprisingly. I prefer the 2/28 Distagon or the GR's rendition. The GR's lens-sensor combo is something very special too, I think.
diglloyd: Pentax 645Z is a “real” camera. My arm got tired shooting these portraits in 20 minutes https://diglloyd.com/blog/2014/20140708_1542-Pentax645z-examples-portraits.html
Ming Thein: None of the Leica 28 options I've used can touch it (but not tried the new 28/1.4 ASPH, I should ask Sean Reid about it). I started doing weights. It helps.
diglloyd: Agreed, Zeiss 28/2 I prefer to. Different.
Ming Thein: Technically terrible though - field curvature and all - but the rendering is glorious.
diglloyd: Ricoh GR lens is really good but I bet it’s all hardware corrected... and so what, it’s a killer combo. Fixed lens cameras the answer to your “matching” thing. https://diglloyd.com/blog/2013/20130718_4-future-is-fixed.html
Ming Thein: I agree - too bad there aren't many options other than the Sigmas, which have terrible workflow.
diglloyd: Yeah, Zeiss 28/2 is classic design, but gorgeous for close/mid range environmental and such.
Ming Thein: For the quantity of throughput I have...workflow trumps that last 5% in IQ. I actually have concerns that a future Otus wide may be too clinical.
diglloyd: That DP2 Quattro... disappointed. Smearing. Ends the Merrill line. Maybe it’s software though (faint hope).
Ming Thein: I was told from an inside source that new SW and DPP are coming in the next week that should fix it.
diglloyd: I have not been successful in processing even one image on my Mac Pro with SPP 6. Every edit window pops up off screen.
Ming Thein: Played with one last couple of days - my printmaster here works with Sigma for various things - I was surprised by how slow it was and how noisy it was, too. Not much improvement over the Merrills that I can see, other than blue color accuracy.
diglloyd: I have some nice martian rocks for you.
Ming Thein: Now I've lost you.
diglloyd: SPP 6 leaves developer hooks in... sleep system... hang with password dialog to debug... shoddy work. Last comment on skepticism of “all will be fixed”. Two years of sending bug reports leaves me very cynical here.
Ming Thein: Is it just me, or do you feel like the first round of consumers are increasingly becoming beta testers these days?
Ming Thein: Yes. D800/D4 left AF issues, E-P5/M1 shutter shock, Leica M240 QC - lugs falling off (!) etc
diglloyd: Product = hardware + software. Vendors don’t get that. I meant that “increasingly” happened a few years ago. Absolutely! Except perhaps Nikon and maybe Canon.
Ming Thein: It just never seemed to be that way in the past. I didn't feel like the whole workflow was 'fragile' and things were broken/ needed fixing. My D200s just worked. My D2x just worked.
diglloyd: Well, I separate some things from manufacturing “surprises”.
Ming Thein: I didn't have to take the damn camera apart just to make it focus properly. I was surprised that my 645Z's mirror was aligned AND needed almost no AF fine tune.
diglloyd: Agreed. But I think we’re talking manufacturing tolerances on very high res here. Tolerances not upgraded to match resolution Nikon AF simply incapable of precision, period.
Ming Thein: I also don't hear as many issues with consumer grade cameras, though whether that's because of tighter automated machining tolerances or the users being less discriminating, I have no idea. Maybe it's worth buying a D3300 or something to find out.
diglloyd: Good results with 645Z focus, when it can actually focus and not hunt.
Ming Thein: That's also a possibility.
diglloyd: Could be lens designs made for higher tolerances for variation and not so good to begin with (in part).
Ming Thein: it also definitely seems like resolution has outstripped the ability of most tolerances to match it. I'm thinking of bodies, not just lenses
diglloyd: Yes. To see that, shoot Otus 55/1.4 on a D7100 or similar, focus with LV. Even that is not easy. Agreed: AF, planarity of sensor/mount (including many lens mount/unmount cycles, etc).
Ming Thein: Speaking of Otus and QC - I'm very, very impressed with how consistent they are. Leica are a bit of a disaster in that regard - as bad as Pentax. I've had 6 copies of the 50 Summilux ASPH, and only two were decent. Coatings separated off my 21/1.4 and 50/0.95. I gave up after that.
diglloyd: Leica M constant battle 3/4 lenses “off”. Ridiculous. Had to wait 2 months for my 18/3.8 SEM, still has same color fringing on left side only.
Ming Thein: I've had the chance to test three Otus 55s - they're identical in every way, as far as I can tell. Sounds like that's not just me, then.
diglloyd: Don’t get me started on 50/2 APO. My replacement is also skewed left/right (on another brand new body).
Ming Thein: I'm actually starting to think handmade is NOT a good thing. There's no way hand tolerances can consistently match or better a machine. Flare flare flare!
diglloyd: I’d agree. Zeiss Otus quality control very, very high. Probably best in industry. Regular Zeiss very good, but some variation. Still, much better than CaNikon.
Ming Thein: I cannot justify paying the $16,000+ (at least here) that an M240 and 50/2 APO would cost. Not when I could get an Otus AND a 645Z for the same money.
diglloyd: Not just flare: left/right skew too. Both copies, original and “hand picked” replacement. Go figure. Don’t forget the special edition version you really really want.
Ming Thein: I didn't see skew in my sample, but the flare was definitely there. The RF alignment...was a disaster. I was taking my camera apart in the middle of a market in Yangon. The red one?
diglloyd: I would like to see that new 28/1.4 though.
Ming Thein: Agreed - but only because I'm a sucker for 28mm. To be honest, my GR gives me better results than any Leica 28-e combo did.
diglloyd: Both 50/2 APOs have focus skewed forward on right. On two bodies for the first, one (brand-new replacement body for the 2nd).
Ming Thein: Leica must love you.
diglloyd: Any 28/1.4, I don’t care about the special edition.
Ming Thein: I can wait for the Otus version.
diglloyd: That’s why Leica always tell me “sure we can loan you X... in 9 months”. (for review).
Ming Thein: Hah! Nikon here do not loan me anything - which is why I've got so many questions on the D810. Apparently I do not merit loaners.
diglloyd: Otus will kick it’s ass anyway. Leica M designs have rampant field curvature for the f/1.4 designs. eg f/8 for the 35/1.4 Summilux at distance and be there. Nor me. No one wants to talk to honest reviewers. Zeiss IMO has the highest integrity in this regard. I have huge respect for them.
Ming Thein: I think part of that is deliberate - the field curvature - because otherwise you can't edge focus accurately with the RF; you've got to center focus and recompose.
diglloyd: what’s a rangefinder? :; (I use the crappy toy-grade EVF on the M240)
Ming Thein: Well, they're just shooting themselves in the foot long term: if everything is awesome, then credibility becomes an issue The Olympus one...
diglloyd: 50/2 APO is the right approach. They need to apply that idea across the line. But then I will have to abandon Leica (cost).
Ming Thein: I already have for cost and reliability. $8000 or whatever they're asking now for a 50/2 is madness. To bring things somewhat full circle again...what's your verdict on the 645Z and D810? Buy, or not buy? Upgrade, or not? Then the bigger, more interesting question is: does anybody really need either?
diglloyd: I am not buying the 645Z but I want to be very clear why...
Ming Thein: Personally, I'd give the 645Z a recommended rating with the qualification that the 'good' lenses need to work for you The sensor is utterly epic though
diglloyd: First, the cost. And for me, there is no ROI on buying one. Second the lens line. Third the D810 serves my particular needs for my site; the 645Z serves no purpose (I run though gear constantly, it would sit there with no purpose). Absolutely I rate the 645Z high. I’d *love* to have one with the 90/2.8 and a good 21/2.8 and something dunno in between.
Ming Thein: Diminishing returns
diglloyd: 90/2.8 alone would be OK. But spend $14K.... ?
Ming Thein: I admit the 'want' factor trumped most other considerations for me; I sold my CFV-39 to pay for it, and have an upcoming project that could use the resolution. But still...it's a tough justification.
diglloyd: Other problem: where would I shoot it? It fills my entire daypack, it’s a beast. Just no fun at all in the mountains. the Live View on the 645Z is a huge plus for any precision work, I would think that would dovetail with some stuff you do.
Ming Thein: Ironically I find it very difficult to justify the D810, even though the D800Es have been my workhorses. Mainly because the ergonomic changes are enough to annoy me (I use that metering switch a lot); I'd have to buy two, spend days sorting out mirrors and focusing screens, and on top of that...well, the D800E still does the job just fine.
diglloyd: No EVF on the 645Z is a problem too... presbyopia increasing nuisance so rear LCD requires loupe, etc. I agree with you, but my needs are quite different...
Ming Thein: Hah. I plan to shoot the 645Z handheld for corporate/ industrial documentary mainly. The D800Es are what I use for precision because of the macros and TS lenses. How is the D810 better with no EVF either? :P
diglloyd: D810 already reducing my error rate (Live View quality, faster turnaround on LV shots, no risk of vibration with the EFC shutter). It is not, but it is smaller and with far superior lens selection in quality and size. 😊 https://diglloyd.com/blog/2014/20140626_2006-NikonD810-thoughts.html
Ming Thein: I think it's actually a very interesting sign that the market is moving this way: both of us would probably be served just fine by either if we had no choice; and the image quality is still miles beyond anything from several years ago. But there's so much choice it makes me wonder how camera makers are going to survive...
diglloyd: It’s about ergonomics, controls, operation, hit rate. In this regard, the Sony RX1R really nailed it for me.
Ming Thein: Didn't at all for me.
diglloyd: (with a Really Right Stuff grip)
Ming Thein: Actually, my highest hit rate cameras are...an Arca Swiss 4x5 and sheet film, and the GR.
diglloyd: In the field error rate for ad-hoc extremely (very very high hit rate). Gotta have the EVF and grip on the RX1R. Then it’s almost error free for me for ad-hoc shooting fun.
Ming Thein: The D800 is abysmal mainly because of shake and focusing. I'd rather have the GR. But I've never been a 35mm person. I'd probably be all over it if it was a 28, though
diglloyd: I’d like Ricoh to make a full-frame GR with 28mm f/2.8.
Ming Thein: Oh yes.
diglloyd: Me too. RX1R should have been 3 focals.
Ming Thein: With the D800E/810's sensor. Like the Sigmas? That approach actually makes a lot of sense. And the FL choices were sensible.
diglloyd: Well, matched lens to 56MP sensor and built in EVF, leaf shutter, built-in flash.
Ming Thein: Too many pixels.
diglloyd: Yes, like the Sigma Merrills. 56MP as 36 output or so will eliminate Bayer issues. Pixels aren’t just about detail.
Ming Thein: Or even half, down to 28MP. Yes, I know. Tonal information, DR and noise, too.
diglloyd: Yes. Any size you want: full, 3/4, 2/3, 1/2, 1/3, 1/4.
Ming Thein: Processing speed issues...
diglloyd: That’s the rub. 11+7 bit IMO no match for D810 14-bit
Ming Thein: I'd actually like to see a 100MP sensor with 4:1 binning - RGB and ND for extended dynamic range.
diglloyd: Not really. D810 files just fine for me. 645Z too. https://macperformanceguide.com/index_topics.html#MacPro2013
Ming Thein: On a full 6x6 chip for Hassy V, while we're at it.
diglloyd: Should be 36 X 2 X 2 (Sony RX100 density) https://diglloyd.com/blog/2013/20130307_3-oversampling-RX100.html
Ming Thein: Try that with the 645Z. It makes my D4 look rubbish at 51,200. In fact, I honestly cannot think of a good reason why I still own the D4 at all. Other than because I like the ergonomics.
diglloyd: Or the Sigma DP Merrills. https://diglloyd.com/blog/2013/20130221_2-stitching-the-SigmaDP2Merrill.html D4 has a velvety look to its images. Very nice. But I don’t want a measly 16MP.
Ming Thein: The D4 has surprisingly high acuity given it still has an AA filter. 16MP was more than enough 5 years ago...our output forms haven't really changed, for the most part. Most people are still using them for social media or small prints.
diglloyd: seems to matter less on lower res cameras.
Ming Thein: I'm probably the only one resolution limited at 10x15" print area with the 645Z.
diglloyd: I personally enjoying seeing things I could not see while there. It’s just plain rewarding and fun.
Ming Thein: Not everybody is like us In fact, most aren't. Or we'd have that EVF 33x44 mirrorless camera with Otus AF lenses...
diglloyd: six feet wide with sigma as your printer knows works well I think. https://diglloyd.com/blog/2013/20130802_3-SigmaDPMerill-printing-really-big-is-awesome.html could be Otus quality a lot smaller as a mirrorless
Ming Thein: True. Curved sensor too perhaps We can dream...
diglloyd: 44 X 33 ml would be hot. Wonder why Pentax does not do it (Ricoh GR MF!) Would be hot, hot, hot seller. Sony is the only vendor likely to do I think.
Ming Thein: Hmm...probably cost? At $5-7000 for a body, hmm. That said, I'd buy one. Good thing photographers are provided with two kidneys and other subdividable, transplantable organs.
diglloyd: which would be a bargain at $7K given what it is (lens + camera) compared to a 645Z
Ming Thein: True. Not a system though. And I was speculating at 7k - it may well be more like 10.
diglloyd: Two focals: 21mm and 28mm.
Ming Thein: I'd rather 28 and 40 or 55
diglloyd: Anyway, D810 great camera, 645Z terrific too, but so huge that it’s not for many: 645Z will just be left behind too often for me. What I’m hearing from readers is that D810 upgrade is worth it to them. It is for me, but maybe not for everyone—all depends on what and how you shoot.
Ming Thein: Looks like I'm going to somehow have to get my hands on one. I really enjoy the 645Z though. And the IQ is another notch up.
diglloyd: Me too. But I call it a “car or house camera”!
Ming Thein: But I agree: size and lenses mean more often than not I just bring one. You don't have 200% import tax on your cars, that's why.
diglloyd: BUT if all I were doing was landscapes or such stuff, and no other systems, I might go with one. That is not my situation. I buy my cars used too.
Ming Thein: Even if used. New has huge tax...used prices are commensurate. A two year old Honda Civic goes for about $30-35k here.
diglloyd: Couple of 645Z things bug me: the modal image review constant waste of time for me. A few others. 645Z has also failed to record images several times. Seems to happen after card format. wow! (car)
Ming Thein: I think there are options as to what you can access in image review - pretty much everything except browse others. No write issues here. Cameras by comparison are tax free...
diglloyd: no options without 3/4 chimping operations to get there and then back to histogram.
Ming Thein: Win some, lose some.
diglloyd: D810 cycles between 1/2/3/4/5 screens, your choice. 645Z cannot.
Ming Thein: I honestly think it's the way you have your playback options set. I can have my basic info + flashing highlights + single button zoom just fine It remembers my last playback info state on review
diglloyd: Fixable in firmware. But K3 has same headache. Big time waster for my shooting. Any flavor you want as long as its vanilla. Problem is cannot get to alternate info without menus presses. Then repeat that to go back to histogram. Too hard to describe here. Does not do it.
Ming Thein: You might be asking it to do something more complicated. Vanilla is fine for me.
diglloyd: I want to be able to cycle between RGB histogram, uncluttered view, basic info, flashing highlights. AFAIK cannot be done.
Ming Thein: Not easily, no. You can have one of those but not all easily.
diglloyd: Nikon D810 does it. And not complicated.
Ming Thein: So does every other Nikon since the D2H
Ming Thein: Playback is the one thing they got right. A lot ...fail. Canon especially.
diglloyd: Not a show stopper. Just an annoyance. Every camera has its share.
Ming Thein: Well, if they didn't, we would stop buying and they'd all go out of business. In any case...it's been great chatting with you, but I'm going to have to call a halt because have to head out to meet a client shortly.
diglloyd: Worth noting: 645Z can Live View most anywhere in frame. That is not a given these days (center only on Leica M, fixed modal on Sigma, etc).
Ming Thein: The Nikons do anywhere also
diglloyd: Fun time! Bye Ming! And Canons and many others. But not Leica M. 😟 See ya. 😊
Ming Thein: It's handmade. Perfection. Just like the RF ;) Until next time! Thanks for the great chat.
diglloyd: Thank you too. 😊 Bye
