New Patent: Canon EF 58mm f/1.4 Lens

Posted on by

Canon has filed a new patent – Canon EF 58mm f/1.4 lens for Canon DSLRs with full-frame image sensors. Nokoton was the first to announce 58mm lens (Amazon) and then followed-up by Nikon 58mm f/1.4G. If it becomes a real product, the new Canon EF 58mm f/1.4 lens will probably not repace the current EF 50mm f/1.2 L USM but it will compete against Nikon’s AF-S NIKKOR 58mm f/1.4G lens.

Take a look at the patent details below translated by Google.
