The Optical Viewfinder Is Not Dead, Canon Patent Suggests

Canon Patent

This Canon patent suggests that despite all the mirrorless hype, and even now that Canon announced the development of a new industry game changer, the EOS R5, there is sill need for an EVF (Optical ViewFinder).

Canon patent application 2020-27113A (Japan, spotted by Hi Lows Note) shows that a big company like Canon is still doing R&D on optical viewfinder implementations.

Canon Patent: 100-400mm f/5.5-7.1 Lens For APS-C Camera

Canon Patent

Here is an inetersting Canon patent for a 100-40mm lens.

Canon Patent Application 2020-027156 (Japan) discusses optical formulas for a 100-400mm f/5.5-7.1 lens. The interesting fact is that this 100-400mm f/5.5-7.1 is for APS-C cameras. For the EOS-M system? We think rather not but it is possible. For sure it seems to be consumer lens.
