In this patent application (2024-061921), Canon is showing off some curious embodiments for some prime lenses. These are full-image circle primes with no image stretching so understandably they would be targetted as higher-end primes. Maybe Canon got tired of my whining on the subject. But what I found most curious is that the focal lengths

The patent states a focal length of 26.62 mm, maybe Canon will round this up to 28 mm.
I still don't understand this focal length.
If you own a 24mm or a 28mm, why should you buy it? WA standard zooms start at 24 or 28mm, existing or future primes are -will certainly be- 24 and 28mm...
Unless this lens is meant for a very specific purpose, I'm at a loss for what to do with this focal...

A 26mm Prime would indeed be somewhat odd and not in accordance with our expectations. But remember, Zeiss has a 1.4/25mm Milvus wich also does not fit to the usual FL for FF. And 25mm Primes at least are common in cine-lenses (Arri, Zeiss, Cooke).
And Hasselblad just introduced a 25mm lens for their ‘medium’ format as well.

If these do have ‘video features’ then canon needs to think about releasing some professional cine cameras with RF.
These are full frame lenses but they don’t have a full frame cinema camera with RF.

I think their departments need to talk to each other.
I'm quite sure they do!

Zeiss has a long 25mm tradition (Biogon, Milvus, Batis, Distagon). Same with 20-21mm lenses. Some companies prefer 20mm, Leica and Zeiss opt for 21mm, No reason, just a choice.

Wich is btw also true for other Standard-FL. Remember all the various 55 und 58mm Primes - instead the "usual" 50mm. And of course the Portrait-FL is not always 85 mm like Canon, Zeiss and Nikon. Leica used to have 90mm - except the 80mm Summilux-R and the 75mm Summicron/lux-M. :)

75 Summilux M: :love::love::love::love::love:
And the 60mm Macro Elmarit, the 180mm Apos, the 250, 280, 560 Telyts.
So, if I think it over, why not an RF 26mm?

I guess you're ignoring the R5C

We have 3 R5c cameras which have been our workhorses for years. But they we only supposed to see us through until a professional camera came out. It’s been 2 years. Our rigs a crazy to make it work as a good cine camera. Cage, rails, v-mount plate with cables, hdmi to sdi coverts with cables, useable monitors with cables. It’s great but it’s an absolute mess.

Could be. But normally Canon would round this up to the "better side".
A 382mm tele will become a "400mm".
A 26 mm WA will become a "24 mm".
We'll see, what patent will come to live at all.

If Canon makes a full-frame 25 mm lens they call it 24.
They use the exact focal length for APS-C lenses.
I think Zeiss prefers to be exact.
