User manual NIKON MD-12 MOTOR DRIVE

[. . . ] Referring to the diagrams on the sides of the clip that show the correct ~vay to insert the batteries, ensure that the positive (+) and negative ( - ) terminals of the batteries are properly positioned. If the batteries are loaded incorrectly, not only will they be depleted--the motor drive could also be damaged. When the batteries are correctly positioned, replace the battery clip. Push the chamber iid down gently until it seats correctly; then, tighten the locking screw on the lid with a coin or similar object until the battery clip fits securely into the battery chamber.

NET ATTACHING THE MOTOR DRIVE Mounting the MD-12 on your camera is simple; the unit has been designed such that it can be attached or removed at any time regardless of whether or not the camera is loaded with film. [. . . ] The FE's automatic exposure capability allows you to follow subjects as they pass through areas of differing brightness, yet still obtain~ correctly exposed results. Although widely varying brightness changes of EV 4 or more may sometimes result in over- or underexposure for the first frame following the transition, this situation is rare in practice and thus likely to be of little consequence to the average photographer. After shooting, make sure that you turn the motor drive off. Note: The camera/MD-12 combination is designed to work smoothly under a wide range of climatic conditions. Sub-zero (centigrade) temperatures, however, have a very severe effect on any mechanism. For faultless performance under these conditions, we recommend that, for continuous shooting, you do not use shutter speeds of less than 1/30 sec. If it is imperative to use shutter speeds of less than 1/30 sec. , switch to single frame shooting. Distributed by WWW. LENSINC. NET FILM REWINDING When the roll of film in the camera has been fully exposed, the MD-12's motor will automatically stop, releasing film tension, with the pilot lamp remaining lit. See your camera's instruction manual for details. MANUAL FILM ADVANCE If at any time you wish to manually advance the film without removing the MD-12 from the camera, turn off the motor drive's power switch after it has finished advancing the film from the previous exposure. below 3, 000, 000), turn the mode selector switch so that the black line (white, on black camera bodies) is adjacent to the line on the camera body. over 3, 000, 000) or the FE, it switches automatically from motor drive to manual film advance operation when the motor drive is switched off. Distributed by WWW. LENSINC. NET DOUBLE/MULTIPLE EXPOSURES Your camera has a special double/multiple exposure provision built-in in the form of the multi-exposure button or lever. Merely depressing this button or lever allows you to superimpose any number of pictures on the same frame. This provision not only continues to function with the motor drive attached, but opens up creative possibilities that are just not possible when the camera is operated manually. When the motor drive S-C selector is set to "S, " the double/ multiple exposure situation is exactly the same as for the camera alone, except that the trigger button on the motor drive is used to trigger the exposure. Remember to depress and hold the multi-exposure button or lever, with your left hand, before you remove your finger from the trigger button. On the "C" setting, triggering the release button, while holding the multi-exposure button or lever depressed, will produce multiple images on the same frame. Either the motion of the subject or your movement of the camera will result in the images being separated, producing an original and interesting effect. Hold the multi-exposure button or lever depressed with your left hand, while holding the camera normally with the right. Remember to release the multi-exposure button or lever just before the last exposure, so that the camera is left ready for the next sequence with an unexposed frame in the film gate. One end of the MC-4 features a plug for connection into the camera's remote control socket while the other end has plus and minus banana-type plugs. For remote control operation, you can attach the banana plugs to a triggering circuit of your own design. The cable can be extended to any length, provided that circuit resistance does not exceed 1 kQ. For longdistance operation, however, you will find that Modulite orfadio control systems are more convenient. For simultaneous operation, you can connect two or more motor-driven cameras in parallel using a circuit containing two or more MC-4 cords, plus additional wiring. [. . . ] As a guide, however, you can expect to be able to expose more than a hundred 36-exposure rolls of film per set of alkaline-manganese batteries. Since batteries have poor low-temperature characteristics, battery performance diminishes considerably as the temperature decreases. This results in slower shooting speed and reduced film transport capacity. Alkalinemanganese batteries, in particular, suffer severely at temperatures below 0 C.
