• 3-Pin Sync Cord SC-22
The 3-pin sync cord can be used with all Nikon and Nikkormat cameras having standard ISO-type hot shoe. When the SC-22 is used with the Nikon F3-series*, FA, FE2, FE, FM2, F-301/N2000, FG, FG-20, or EM, the camera's ready-light in the viewfinder operates, so you can take pictures without removing your eye from the viewfinder. In addition, with the Nikon F3-series, FA, FE2, FE, F-301/N2000, FG, FG-20, or EM camera set for automatic operation or at certain manual shutter speeds, the proper sync speed is automatically set by turn- ing on the power supply for the Medical-Nikkor 120mm f/4 IF lens . (For details about automatic switchover to flash sync speed, refer to your camera's instruction man- ual.)
To use the 3-pin sync cord, first plug one end into the sync socket on the lens barrel by aligning the arrow on the plug with the ~ mark next to the socket. Then, slip the other end into the camera's hot ~hoe until it stops, and tighten the attachment screw.
*Use of the Flash Unit Coupler AS -4 or AS -7 is required.
