I was talking about an SLR mount. Funnily enough, I used to have a 50mm .95 range finder lens for a while...a long time ago. My point was...if Canon wanted to release new exciting glass...they did it before with the EF mount and the 50mm f1.2...why couldn't Canon do the same for the RF mount? Why not a rf 35mm f1.0? Even expanding the f1.2 range would be a revolution.??? Canon had a 50/0.95 for its rangefinders for like 20 years at that point, and 50/0.7's existed even if in small numbers.
