Canon Command Back 70

Designed exclusively for the Canon T70, the Command Back 70 is equipped with a command function that controls the camera in various timer modes such as a self-timer mode, interval timer mode, long release timer mode and frame counter setting mode. It also allows you to record data such as the day, month, year, time or frame counter directly on the film. The Command Back 70 can be programmed by combining the modes of the timer control function and using them together with the data recording function. Uses a (2-CR2025) battery.
