Shutter
The vertical focal plane shutter has rubber-coated curtains. Speeds are set on a single
non-rotating selector. Through a special stabilizing device, there is uniformly balanced
exposure across the large film area even at high shutter speeds.
High quality miniature ball bearings are used. The shutter curtain travels across the
55mm film gate in 15-16 milliseconds. The X setting for electronic flash (strobe)
represents 1/40 second. Intermediate shutter speeds can be selected between the
following speeds: 1-1/4 1/8 -1/30 1/60-1/1000
1 - Shutter Speed Selector
''B'' stands for ''Bulb''; press to open, release to close shutter. ''1'' is one second; ''2'' is 1 / 2
second; ''1000'' is 1 /1000 second, etc.
''X'' represents 1/40 second and is the fastest shutter speed with which electronic flash can
be used. Any faster settings will result in partial non-exposure. (see ''Flash'', page 19).
