Operating Details
Exposure
As a general rule for all shutter speed settings
except
B,
you should keep the release button
depressed until the lens shutter has opened and
closed fully. This
is
especially important
at
shut-
ter speeds from 1 s to 1/15s.
If
you relax the pressure
on
the release button too
soon, the auxiliary shutter will terminate the
exposure prematurely (see page
14,
'Warning
Signal').
You can see the auxiliary shutter, which consists
of
two blinds, covering the rear opening of the
camera body.
Time Exposure Lock
The time exposure lock has two settings:
0,
where it
is
disengaged and
T,
where the de-
pressed release button locks in the depressed
position until the lock
is
returned
to
the 0 setting.
The winding crank cannot be advanced until the
lock
is
reset to O.
You
can use the T setting for time exposure when
the shutter
is
set at
B.
The time exposure lock cannot
be
used with a
cable release.
