This setup was used for a research lab work. Using an MT-2 Intervalometer, it recorded images for subjects once every 15 minutes for an entire week without running out of film. The film magazine has the capacity of 750 pictures. The MF-2 requires an MA-4 AC/DC converter to run, and an MC-2 cable to connect to MA-4 to the MF-2
The MF-2 has been called "Might Joe Young" by some websites. It is not to be confused with the much smaller, and more common 250 film capacity back, the MF-1.
