And yet another Canon patent, as usual spotted by Hi Lows Note. A 35mm f/1.2…
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.
