To reset the camera for full-aperture metering with an
FD lens, push the multi-purpose lever lock to the
white dot. The multi-purpose lever will spring back
automatically to its upright position.

How to "Average" Exposures
When measuring a subject influenced by greatly
different light intensities, take two measurements,
one each of the darkest and lightest parts, and obtain
the average value for the two readings. Then, set the
f/stop or shutter speed at this average value.

At given film speeds, the built-in exposure meter
couples within the f/stops and shutter speeds as
indicated in the chart at the left. For example, when
using the Canon FD 50mm f/1.4 lens at ASA
100, the exposure meter couples fully within the
range of EV 3, f/1.4 at 1/4 of a sec. (the first num-
ber as read off the row labelled "ASA 100") to EV
18, f/11 (read off the bottom row) at 1/2000 of a
sec. (again read off the "ASA 100" row, but this
time read the last number). Thusly the first number
of a row indicates the longest shutter speed possible
at a given film speed with the aperture fully open
while the last number denotes the fastest shutter
speed possible with the f/stop used being read from
the bottom row as the number directly under the
fastest shutter speed.
