Motor Drive
One of the most exciting new accessories for the F3 is the MD-4 Motor Drive. This amazingly compact and stream- lined unit attaches to the bottom of the camera in seconds and advances the film either singly or in sequence form up to a rapid 6· frames per second-making it the fastest regular production motor drive on the market today. Actual controls have been reduced to only those neces - sary for convenient operation . In addition to the electro- magnetic trigger button (which also turns on the camera's meter when depressed halfway), there is its concentric S-C (SINGLE/CONTINUOUS) mode selector, a battery check button and LED indicators, two interlocking re - wind slides for automatic film rewinding, and a sub- tractive frame counter which stops the motor at the desired number of frames for use in cold weather. 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 .
