Instruction Manual for MD-4 Motor Drive - Detailed Features Part 1

Anatomical Grip The MD-4 features a new anatomical grip to permit the photographer to shoot either horizontal or vertical pictures comfortably. For horizontal shooting, hold the grip so that your thumb is behind the camera and your forefinger is on the trigger button. In this way, you can change quickly from horizontal to vertical shooting. However, another way to hold the motor drive vertically is to balance the grip in your palm with your thumb over the trigger button. This position is recommended for one handed shooting over an extended period of time, such as when using a bracket-mount flash unit off-camera.

S-C Mode Selector Concentric with the trigger button for easy access, this dial sets the motor drive for either single frame (S) or continuous (C) operation. There is also a lock (L) position. At "S" (Single Frame) At all shutter speeds, except "B" and "T," the motor drive trips the shutter and winds the film in a single sequential step. At the same time, one LED lights up to indicate film advance.

At the "B" setting, when the trigger button is pushed, the shutter fires and remains open until you take your finger off the button. Then the film advances automatically to the next frame. At "T," the shutter remains open until the shutter speed dial is rotated off the "T" setting.


Note: With the camera's power switch turned on, you can take motor driven single frame shots by using the camera's shutter release button. When you depress the button, the shot is taken, and when you release pressure from the button, the film wound to the next frame. This occurs with the S-C mode selector set to either "S" or "C."

At 'C' (Continuous)

As long as you hold the trigger button down, shots will be taken rapidly in succession. Any shutter speed setting, except "B" and "T," can be used. At shutter speeds slower than 1/125 sec., the firing rate automatically slows down to match the shutter speed in use.

Multiple Exposures Motor-driven multiple exposures are possible by holding the multiple exposure lever in position while firing off a short burst. After you're finished, make a blank shot by covering the lens with a lens cap. This will advance the film to the next unexposed frame without adding another shot to the multiple exposure just completed.

Caution: Do not hold down the backup mechanical release lever while shooting on Continuous, as the shutter will not open properly. But it is tempting as the MD-4 will fire at very high speed film advancing.At 'L' (Lock) The trigger button is locked and the motor drive will not operate. However, by turning on the camera's power switch, you can use the shutter release button to trip the shutter and advance the film manually just as if the MD-4 were not attached.

Trigger Button The MD-4's trigger button, because it is an electromagnetic release, operates in exactly the same manner as the camera's shutter release button. It not only trips the shutter but serves as a meter switch as well.

When depressed halfway, it turns on the meter and activates the LCD exposure information in the viewfinder. If the button is not touched again, the meter will turn itself off automatically after 16 sec. to conserve battery power. With the MD-4 attached, it makes no difference whether the camera's power switch is turned on or not. In fact, you might find it easier to leave the switch in the OFF position and control the camera's meter entirely with the trigger button.
