LOADING THE CAMERA- continued
Film-Plane Indicator
The (~) mark on top of the camera body shows the
exact position of the film plane. This is important to
know when measuring the fUm-to-subject distance,
especially
in close-ups and macrophotography.

Film-Advance Lever
The fUm-advance lever simultaneously advances the
film, cocks the shutter and operates the frame counter.
It also serves as an on-off switch for the exposure
meter.
Stroke the film-advance lever with the right thumb in
a single
stroke. A built-in locking device prevents the
shutter from being released unless it is fully cocked
and the film has been advanced a full frame.
The film-advance lever springs back to its original posi-
tion, with ample clearance for the thumb, after each
stroke. However,
the meter will remain in the "on"
position until the lever is pressed flush against the
camera body.
Caution: Be careful not to push the rewind button (on the
camera's baseplate) during ftlm advance operation. Should
this occur , temporary stoppage of ftlm transport and double
exposure of the negative may result.
