Operation; Single-Frame Shooting - Nikon MD-15 Instruction Manual

OPERATION

The camera/MD-12 combination operates in virtually the same
manner as the camera on its own. Please refer to your camera's
instruction manual for details. When the MD-12 is attached,
leave the film advance lever flush with the camera body. Then,
when the motor drive's power switch is turned on, the camera's
meter can be activated by halfway depressing the trigger but-
ton. After releasing your finger from the button, the meter will
remain on for approx. 50 seconds giving you enough time to set
the correct exposure or adjust the controls. Then the meter will
turn itself off automatically to conserve battery power.
With the motor drive attached all exposures should be made via
the trigger button on the motor drive grip. Concentric with this
triggering button is the motor drive S-C selector, giving you a
choice of either single frame (S) or continuous (C) shooting. To
set the motor drive to either S or C, depress the lock and turn the
selector to the required setting.
Single-frame shooting: In this mode, depressing the trigger but-
ton on the motor drive grip fires the shutter, advances the film
one frame and cocks the shutter. You can lift your finger from
the trigger button even before the exposure is completed since
the electronic interlock prevents the film from advancing until
the shutter has completed its travel. The usable shutter speed
range when the MD-12 is set at "S" is from 1 second to 1/1000
second with the FM. With the FE, in addition to the automatic
setting (AUTO), you can set any of the marked speeds includ-
ing M90. The "B" setting cannot be used with either camera.
