Canon 318 M - Manual (Page 7)

Accurate Exposure Metering
Accurate exposures can be obtained even
when zooming because this camera is
equipped with a TTL exposure meter, using
a CdS photocell, which measures light pass­
ing through the lens.
World’s First Built-In 1C Power Circuit
A highly accurate exposure meter, using a
monolithic 1C, is incorporated in the metering
circuit. This checks the voltage fluctuation
and makes possible very accurate exposure
metering Three 1.5V penlight batteries are
commonly used as power for film drive,
automatic zooming, and metering for the
convenience of the user.
Sharp and Clear Single-Lens Reflex Type
Viewfinder
The viewfinder is of the single-lens reflex
type, using a total reflection mirror. There­
fore, subjects can be easily and clearly
seen even under dark conditions. Under­
exposure warning mark and macro filming
indicator also built into the viewfinder.
Common Use of Power Source
Three 1.5V penlight batteries are commonly
used as power for film drive, automatic
zooming, and metering for the convenience
of the user. The metering circuit has a special
built-in voltage stabilizing circuit for check­
ing fluctuation and maintaining a very ac­
curate exposure.
Compact, Lightweight
The 318M is compact even with a built-in
zoom lens, and it weighs only 470 grams
(1 lb.-9/16 02 ).
