A new Nikon 100mm F2.5 Medium Format lens patent appears on egami. Last months, there were rumors on Canon planing for medium format cameras, seem Nikon will also develop medium format cameras in near future.
A new patent from Canon now listed on Egami. This new lens patent is Canon EF 50mm f/1.8 IS USM lens. This lens could be the replacement of current 50mm f/1.4 lens. We had heard replacement of 50mm f/1.4 since last year. CR also said a new 50mm f/1.2L lens is in testing.
