Frame Counter and Film-Load Reminder

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.

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.

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.

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.
