BUILT-IN EXPOSURE METER
The Canon 7S Exposure Meter, which is the match-
needie type, is coupled to the shutter dial. The
exact exposure may be easily determined accord­
ing to the brightness of the subject to be photo­
graphed. There are two ways of determining the
exposure,
either by first selecting the shutter
speed or by first selecting the lens aperture.
