Nikon MC-36A process_Black & White but if you're looking forThe Nikon MC 36A is a sophisticated wired remote control for Nikon cameras with 10 pin connectors. It'll fire the shutter when you mash the button, as you might expect, but it also works as an intervalometer and a timer, and allows you to select exposure times of up to nearly 100 hours. In excellent condition. Note: This inventory image shows a Nikon MC 36. Actual item will vary slightly, in the sense that it'll be an MC 36A.
