The Command Back El pro
vides the photographer with
sophisticated timer control
operations and allows various
types of data imprinting to be
carried out. You can capture
periodic scenery changes over a
fixed length of time, enabling
ecological or astronomical photo
graphic studies. A special self-
timer function releases the shutter
after a predetermined period of
time. The interval timer releases
the shutter at fixed intervals,
spaced anywhere from 1 second to
23 hours 59 minutes apart. The
long release timer holds the shutter
open for a preset period of time
during bulb operation. And the
frame counter setting stops the
camera after a set number of
exposures has been made. Data
imprint functions include the date,
time of day, a frame counter
number, or an arbitrary 6-digit
number plus the letters A through F.
When the Command Back El is
being used, functions assigned to
the quick control dial are handled
by the main electronic input dial in
conjunction with the exposure
compensation button.
