Here we have a Nikon MD-4 Motor Drive for Nikon's professional F3 and F3HP 35mm film SLR cameras. This winder is in excellent condition and is fully functional. 

Battery compartment is clean. 

THe Nikon MD-4 offers effortless film advance and rewind when fitted to your F3 or F3HP. Choice of single-frame or continuous firing is offered through a selector knob. Secondary shutter release button activates the camera's exposure meter (just as using the regular shutter release would), and the camera can be powered by the batteries in the motor drive if the camera batteries are dead. 

Burst mode operates at up to 6 frames per second. Automatic winding stop occurs when the film end is reached, a warning light illuminates, and the film is then rewound in under 8 seconds. 

Does not come with batteries.

Winder will be packaged securely and shipped immediately.
