Progress in the speed of focal plane shutter
The speed up of the shutter has taken surprisingly much time among the rapidly developing camera mechanism.
Regarding the focal plane shutter, "Leica" with horizontal-travel cloth curtain shutter and "Contax" with vertical-travel metal curtain (blade) shutter were competing and attained the highest speed of 1/1000 sec., and 1/1250 sec. respectively in 1930s, and in 1960 "Konica F" first attained the speed of 1/2000 sec.
Regarding the lens shutter, the highest speed was 1/3000 sec. with "Minolta V3" (1960), but it had a restriction on usable aperture stop value when selecting the higher speed (e.g., when selecting 1/3000 sec., only f/8 to f/22 can be used).
Except that, the highest shutter speed of general use cameras was 1/2000 sec. until 1982 when the Nikon FM2 was put on the market.
