SETTING THE EXPOSURE
Activating the Meter
The OLYMPUS OM-1 metering system
is directly coupled to the shutter speed
ring, aperture ring and ASA film speed
dial.
To activate the meter, move the meter
switch lever at the top of the camera to
the "ON" position. To prolong battery
life, it's a good idea to return the lever
to the "OFF" position when the cam-
era is not in use.
Preselecting the Shutter Speed
Should you wish to select a shutter
speed to meet a specific photographic
situation (for example, to stop fast
action, eliminate camera shake, etc.):
1) Turn the shutter speed ring until
the desired speed is opposite the red
reference dot on the camera lens.
2) Look through the viewfinder and
turn the aperture ring until the needle
lines up in the center of the index. For
fine exposure adjustment you can use
any intermediate F stop position on
the aperture ring.
3) If the needle will not align proper-
ly, select a new shutter speed. To
correct over-exposure (+), try a faster
speed; to correct under-exposure ( – ) ,
try a slower speed.

Preselecting the F Stop
Should you wish to preselect the F
stop (for example, to control depth of
field for greater creative impact):
1) Turn the aperture ring until the
desired F stop is opposite the white
index mark at the front of the lens
barrel.
2) Look through the viewfinder and
rotate the shutter speed ring until the
needle lines up as close as possible to
the center of the index. Make sure that
shutter speed meets the other require-
ments of the situation.
3) Make the final exposure adjustment
by turning the aperture ring slightly
until the needle aligns exactly in the
center of the index.
