Canon RF 24-70mm f/2.8L Aperture Series @ 24mm: Cottonwoods along Irrigation Ditch

This aperture series from f/2.8 to f/8 is with the Canon RF 24-70mm f/2.8L IS USM at 24mm. It discusses overall performance, and especially the forward focus shift which affects all of the zoom range.

Focus position was chosen to optimize total sharpness, and this is explained as to why/how.

Canon RF 24-70mm f/2.8L Aperture Series @ 70mm: Curious Cattle under Cottonwoods

I like to confirm results on different scenes, to see consistency of behavior. That gives a high degree of confidence in findings.

This aperture series from f/2.8 to f/8 with the Canon RF 24-70mm f/2.8L IS USM at 70mm confirms a pronounced forward focus shift as seen in Cottonwoods and Cattle, but it is even more obvious.

Need up to 64TB SSD in a Compact Enclosure? OWC Mercury Pro U.2

I wasn’t aware that the state of the art had now risen to 64TB in a single relatively compact external Thunderbolt/USB-C enclosure.

OWC Mercury Pro U.2 Dual for up to 16TB U.2 SSD, or 64TB NVMe M.2

Granted, few photographers need 64TB of any kind, but some do, and videographers certainly can make use of it once 8K is being used (eg film industry).

And if you have the bucks, what a nice solution to get rid of hard drive noise!

I’d love to have one huge 32TB or 64TB SSD for convenience, but it’s not in my budget. But I have something in the same genre: on my 2019 Mac Pro I have OWC Mercury Accelsior 4M2 16TB PCIe SSD, dual 8TB OWC Thunderblade, and one 8TB internal Apple SSD).

And as of today, you can configure a 16TB unit for only about $2400, using the 0TB enclosure and dual 8TB U.2 SSD at $978 each.

Canon RF 24-70mm f/2.8L Aperture Series @ 56mm: Cottonwoods and Cattle

This aperture series from f/2.8 to f/11 with the Canon RF 24-70mm f/2.8L IS USM at 56mm shows a pronounced forward focus shift which has major implications for total image sharpness unless it is compensated-for. Results here were confirmed with other series over the zoom range—consistently strong focus shift.

Ease Into Medium Format with the Fujifilm GFX-50R for just $2999 ($1500 off)

re: The Camera Market is Down to Two 35mm Format Contestants: Sony A1 and Canon TBD
re: Sony A7R IV: Which High-Speed and High-Capacity SDXC Cards Are Best?

Fujifilm GFX-50R

Too pricey to take the $6000 plunge with the Fujifilm GFX100S ?

Ease into Fujifilm medium format at a 35mm price, with the Fujifilm GFX-50R, now $2999 (discounted $1500, $500 more than last month). See items below.

That’s less than the Sony A7R IV sold for most of its tenure.

Add one lens to start, either the Fujifilm GF 50/3.5, or the Fujifilm GF 30/3.5. Enjoy. Make sure to use the B&H Payboo card to save the sales tax in most states.

Hopefully the $500 discounts that have been seen repeatedly last year will crop up again soon; bookmark the Fujifilm medium format wishlist page and check it periodically.

We are in a transition time to the Apple M1 Macs. I expect to receive the Apple MacBook Pro M1 Max for review around December 20.

If you need a powerful Mac now, get the iMac 5K, specifically one of these configurations. Buy it with 8GB memory, then add 128GB of OWC memory. 128GB will serve you exceptionally well for many years to come.

Load up your iMac with 128GB as 4 X 32GB, or your Mac Pro up to 1536GB!

Big and fast SSDs

Eliminate the 'spinners' for a silent environment where disk speed disappears as a factor.

With high-capacity SSDs, you are bascially paying for the flash modules as the primary cost-driver. While expensive compared to hard drives, they are silent and should deliver years of trouble-free use.

I use one 16TB OWC Accelsior 4M2 as my primary storage on my 2019 Mac Pro.

I have two of the 8TB OWC Thunderblades. Outstanding for external fast storag that can be carried to/from job sites or just used daily!

Hard drives

I use 14TB and 18TB Toshiba drives. They are fast, quiet, and I’ve never had a failure.

See: Big and Fast Hard Drive for Photography and Videography

I use five OWC Thunderbay 4 units for backups (now that my main storage is all SSD). Cost aside, no photographer need evert be concered with storage capacity!

Back from Trip, Mercedes Sprinter Fails

The morning dawned and I was plotting a high-altitude hike under the best conditions in ten days. Really awesome lighting. But 20 minutes in, my Mercedes Sprinter decided it was going to end those plans.

So I had little choice but to drive home without stopping, not even for food or fuel, as 10 starts would brick the entire vehicle.

Mercedes Sprinter Ends My Trip: “10 Starts Remaining” after OBD2 diagnostic code U010E “Lost Communication with Reductant Control Module”

I’ll be publishing of stuff on the Canon EOS R5 and its lenses soon, after a day or two of getting organized.

Canon RF 15-35mm f/2.8L Aperture Series @ 24mm: Ancient Log

This series from f/2.8 to f/11 shows how the rearward focus shift of the Canon RF 15-35mm f/2.8L IS USM at 24mm should be taken into account when choosing focus position for close subjects.

The lesson here is “know your lens behavior”. Doing so means that focus can be tweaked for total sharpness that is much better placed over the desired region.

This series from f/2.8 to f/11 explores performance of the Canon RF 15-35mm f/2.8L IS USM at 27mm, which is in the middle of the zoom range and thus likely to be relatively low in distortion and high in overall performance (wide angle zooms are typically strong from the wide end to the middle of the range).
