Canon Patent Application: Canon RF 15-35mm F4L
This is a lens I'm certainly waiting for. We have seen rumors that an ultra wide F4 lens is coming out in 2021. Would I get one of these. I'm waiting for this before jumping into the RF mount to be honest.
Canon states;
The present invention is compact, and it is an object of various aberrations including chromatic aberration to provide a well corrected zoom lens.
Make it happen Canon ;)
The 15-45mm lens design looks more realistic with a 19mm back focus distance than the 16-35mm F4 lens with the rather short back focus distance.
