I agree that Nikon did not invent the motor drive, interchangeable viewfinder, TTL metering, focusing screens, instant return mirror, 250 exposure backs, but I feel that Nikon put a total packet together. When I bought my first F I had a rather complete Pentex outfit, and a Miranda with a critical focus finder with a bellows and several lens. The F replaced both (I kept the Pentex and still have the kit) cameras. Exacta, Miranda, Alpha, and Pentex all had parts of a total system but Nikon I think was the first with the total 35mm system.
