Program curve
If correct exposure is impossible at
the shutter-speed/aperture combination
selected by the camera for the existing
lighting conditions, the display will blink,
and the light balance will indicate the
departure from correct exposure (over a
range of ±1 EV in one-third increments).
Should the difference exceed 1 EV, the
entire light balance will blink.
Note:
The optional MasterWare allows the basic
shutter speed for programmed AE to be
chosen and varied over a range of 30 s
to 1/500 s (for PQ lenses) or 1/1000 s
(for PQS lenses) so that it can be fi ne-
tuned to suit the work in hand. As a result,
there are fourteen additional versions of
the program.
