And yet another Canon patent, as usual spotted by Hi Lows Note. A 35mm f/1.2 lens for the EOS R system.

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.
