accurate exposure. The accurate exposure is auto­
matically determined by simply rotating the aperture
ring to match the needle to the index mark both
of which are visible in the viewfinder window.
The meter can be employed in oil filming speeds,
and aperture readings of the Canon Reflex Zoom
8-3 for all films with sensitivities from ASA 10
(DIN 8) to ASA 320 (DIN 26); for ASA 640 (DIN
29) film all readings except speeds 8 and 1 2 fps.
(4) ASSURED FILMING MECHANISM
The range of filming speeds from 8 to 64 frames
per second are available with this camera.
The single frame exposure is also possible.
The exposure lever is equipped with a safety lock
as well as a running lock which enables continuous
picture taking without having the exposure lever
kept depressed with your finger.
(5) CLOCKWORK SPRING MOTOR
Like a watch, the spring motor with a ratchet
wheel enables you to wind without releasing your
grip on the handle. Uniform speed is maintained
throughout.
A warning signol sounds approximately every 3 sec.
(50 frames or 7 1/2 inches in length) before the
spring fully runs down.
(6) SELF-RESETTING FILM COUNTER
In addition to the film counter indicator dial which
shows length of the film exposed, a click signal
sounds as every 7 1/2 inches of film is exposed
for accurate counting while the picture taking is
in progress.
The indicator automatically returns to " S " or
starting position os the side cover is opened. If
you want to keep the same footage shown on the
indicator dial even after the side cover is opened,
press the film counter control button adjacent to
the counting indicator when you open the side
cover.
