We have another optical formula patent for lenses that are likely to reach the market some time in the near future. This time we have formulas for a Canon RF 14mm f/1.4L IS USM & Canon RF 24mm f/1.4L IS USM.
A fast RF L prime has been long rumoured, and an RF 24mm f/1.4L IS USM is an obvious missing lens in the RF system.
Canon RF 14mm f/1.4L IS USM
- Focal length: 14.30mm
- F-number: 1.44
- Half angle of view: 56.5°
- Length Overall: 123.69mm
- Back Focus: 12.15mm
Canon RF 24mm f/1.4L IS USM
- Focal length: 24.48mm
- F-number: 1.44
- Half angle of view: 41.47°
- Length Overall: 108.53mm
- Back Focus: 13.46mm

I absolutely cannot wait for these lenses. Once we get these and an RF 35 1.2 I’ve got my desired lenses for RF! In love with this post.. can’t wait till these drop!
I am a bit on the fence about the 50/1.4 vs the 50/1.8. I do not think it would be for me since 50mm is not a focal length where I look for tack-sharp quality. USM is nice though, but nothing that would make me upgrade.
So, I cannot imagine Canon introducing a 1,4/14mm and not paying attention to coma. The price will be a different affair...
The main part of the milky way of the center bulge you can easily fit into 35mm. I did that with the EF 35 IS:
So it would be much better, if I could use f/2 or even f/1.2 of an RF35mm. 29mm entrance pupil would bring out so much more stars, not only the possible decrease of exposure time....
But coma is the key issue always... But if they build IS inside an 14mm I don't know what the reason is? Handheld astro without tripod? For architecture you can profit with an IS, but there you use f/5.6 or more always,...
What am I missing?
Does anybody have an idea how big this lens would be? Filter size? Weight? Any guesses.
Of course, I’d probably have to rethink my lens line up and sell a few so I can pay for such a unicorn lense…
I like the RF 35mm F1.8 for nightsky/ cityscapes at night as well. A very capable lens :)
I am reading that correctly???
Dang!
I wouldn't even bet on a 20mm L prime. My impression is the focal length has limited popularity, and Canon might fill the hole between 14mm and 24mm with the rumored ultra wide L zoom.
The EF 24 is nowhere near as sharp as Sonys 24GM.
The 35 GM is still slightly sharper than the EF.
If it’s just a matter of changing the focusing motors and the rest of the electronics, then why is it taking so long to get a 35 out to market?
I hope they do update the formulas to give us something magical.
The 50 1.2 is for very different needs, great as well.
I do see many more relevant gaps in the Canon RF lineup,
- i.e. FL shorter than 15mm, faster than 2.0
- primes below those 400 2.8 /600 4.0 but faster than 600 f11
- RF L anywhere between 20 and 28mm
For the 14mm, the Sigma art is a great lens at ~$1300. This one would be faster at 1.4 vs. 1.8. So adding the canon premium over Sigma, plus the wider aperture, plus the RF premium over EF....that could be a $2500 lens. I'd rather have a second body if I were going to spend that on a low use Astro lens.
