So, I was thinking about my favorite cameras, and I realized most of them came from the 1970s. The Canon F1 premiered in 1971. The Nikon F2 and Olympus OM-1 came out in 1972. Pentax ditched the M42 mount in the mid '70s. The Multimode Minolta XD-11 came out in '77. What do you guys think was the best (most important/biggest leap) decade for 35mm camera development?
