Canon has filed a new patent in Japan. The application is for RF 24-70mm f/2.8L IS and RF 24-300mm f/4-5.6L IS USM lenses designed for Canon full frame mirrorless camera system.
EOS R is the first camera to feature the RF lens mount with a 12-pin connection, flange back distance of 20mm and a wide 54mm mount diameter enabling even greater flexibility in lens design.
