This is a lens rumored since long. And a lens we never doubted would come to the RF mount: the Canon Rf 35mm f/1.2L.

This is a lens that will not be missed in Canon’s RF lineup. A pertinent Canon patent application has also already been spotted. Once more the global pandemic is made responsible for the fact the RF 35mm f/1.2L wasn’t already released. Expect this lens to get announced towards the end of 2021, maybe along with the Canon EOS R3.

Canon patent 2021-60475A (Japan) discusses various optical designs for a 35mm f/1.2 lens for the RF mount. This is definitely a lens we are going to see in the RF lens lineup. A 35mm f/1.2 for sure is going to be released.

Canon Patent: RF 50mm f/1.4 and RF 35mm f/1.4 Lenses For EOS R

Canon Patent

Another Canon patent dealing with lenses for the RF mount, i.e. for Canon’s full frame mirrorless system EOS R.

Canon patent application 2020-181071 (Japan) discusses optical formulas for an RF 50mm F1.4 and an RF 35mm f/1.4 lens. This patent application is particularly interesting since 50mm f/1.4 and 35mm f/1.4 are two very classic lenses for a full frame system.

The patent application seems to reveal a modern and complex optical design with front and rear lenses for optical correction. Moreover, we think it has internal focusing, a small size and a very fast auto-focus. Another two lenses that might go into production.
