Frame Counter and Film-Load Reminder
The frame counter located in the hub of the
film-advance lever shows the number of frames
which have been exposed. It resets itself
automatically to two frames before zero when the
camera back is removed. There are red indicators
for numbers 0, 20 and 36, and the frame counter
stops at the 36 mark. The filmload reminder
opposite the frame counter is set manually by
means of an indicator pin to serve as a reminder of
the number of exposures on the film in the camera.
Film-Speed Reminder Dial
The film-speed reminder dial is located on the camera baseplate. It can
be set manually to indicate the type of film (color or blackand-white)
and ASA rating of the film loaded in the camera. "E" represents
empty.
Film-Plane Indicator
The exact position of the film plane can be determined by picturing an imaginary line drawn along
the top edge of the digits which make up the camera serial number. This is important to know
when measuring the film-to-subject distance, especially in close-ups and macrophotography.
Film-Advance Lever
The film-advance lever advances the film, cocks the shutter and operates the frame counter with a
single stroke of 136° or with a series of short strokes. A built-in safety device prevents the shutter
from being ret leased until it is fully cocked. The lever is designed so that it springs back when
released but does not strike the camera body. A 15° angle of clearance allows the thumb to be
inserted for easy, comfortable film advancing. The lever folds flat on top of the camera for storage
in the eveready case.
