And here is yet another Canon patent discussing optical formulas for lenses for the EOS R full frame mirrorless system.

Canon patent application P2021-71624A (Japan) discusses optical designs for a 20mm f/1.8 lens and a 23mm f/1.8 lens for full frame mirrorless systems. That’s the RF mount. The patent was spotted by Hi Lows Note.

Canon Might Release a 60mm f/1.0 Lens For The RF Mount

60mm F/1.0
View Post

A rumor popped up in our inbox: Canon working on a RF 60mm f/1.0 lens. Plausible?

We did not get any specification for the allegedly upcoming RF 60mm f/1.0 lens. we are a bit out in the rain here. Also, we are a bit surprised by the focal length of 60mm instead of more common 50mm. Wouldn’t it make more sense to bring the legendary Canon EF 50mm f/1.0L to the EOS R system? But maybe the optical design possibilities offered by the RF mount suggest a 60mm is the better option. In any case, it wouldn’t be the first time Canon surprises us.

All in all we think an RF 60mm f/1.0 is definitely possible. Having already an optical masterpiece with the RF 50mm f/1.2 it would probably not make much sense release another optical masterpiece with the same focal length and the “only” benefit of having f/1.0 vs f/1.2. A new 60mm lens would be a different matter, I guess.

All ideas are welcome.

Canon Might Announce More RF Mount Super-telephoto Lenses In 2021

RF 600mm F/4L Super-telephoto
View Post

The Canon RF 400mm and RF 600mm, both announced last week, might not be the only super-telephoto lenses for the RF mount to get released in 2021.

According to a new rumor, at least two more super-telephoto lenses are in development. A Canon RF 400mm f/4 DO IS USM lens might get announced and it could be the smallest and lightest of its kind, with a redesigned optical formula for the RF mount system. A Canon RF 200-500mm f/4L IS USM might also get announced. No more information on this one but it might not have a built-in teleconverter (as the EF 200-400mm f/4L IS USM 1.4x does).

Stay tuned, and stay safe.
