Motor Drive MD-4
One of the most exciting accessories for the F3AF camera is
the Motor Drive MD-4. This amazingly compact, iight, and
streamlined unit attaches to the bottom of the camera in sec
onds and advances the film either singly or in sequence up to
6* frames per second—making it the fastest regular production
motor drive on the market today. Actual controls have been re
duced to only those necessary for convenient operation. In
addition to the electromagnetic trigger button (which also turns
on the camera’s meter when depressed halfway), there are its
concentric S-C (Single/Continuous) mode selector, a battery
check button and LED indicators, two interlocking rewind slides
for automatic film rewinding, and a subtractive frame counter
which stops the motor at the desired number of frames. Eight
AA-type penlight batteries fit into a quick-release clip housed in
the base of the motor drive. An optional NiCd battery pack is
available for use in cold weather or when you want the fastest
possible firing rate. Once you attach the MD-4 to your camera,
you’ll never want to take it off.
The Firing Rate Converter MK-1
is available as a special
accessory for a motor-driven F3AF. It screws into the tripod
socket of the MD-4 and plugs into the remote terminal to pro
vide three firing rates—1,2, or 3 frames per second—allowing
you to operate the motor drive on continuous while the camera
focuses automatically. It has its own handy trigger button for
use in vertical-format shooting.
The Magazine Back MF-4
for shooting up to 250 frames with
out changing film is also available as an option.
'Possible with NiCd battery pack at 1/125 sec. or above with the mirror
locked up.
