Canon EF 50mm f/1.8 IS
A patent has show up showcasing an EF 50 f/1.8 IS lens. Could this be the replacement to the 50 f/1.4? We had heard about this lens existing last year. While some may desire a direct 1.4 replacement with IS, I think Canon may want some separation between the EF 50 f/1.2L and the next 50 in the lineup. We’ve also heard of a new EF 50 f/1.2L design being tested.
