The MF-1 is a viewfinder camera made by Yashica in 1979. It is very like the 35 MF of about two years earlier. It has an unnamed 38 mm f/2.8 lens, with scale focusing using zone symbols, and programmed automatic exposure using a CdS meter cell mounted inside the filter ring of the lens. It has a similar built-in flash, retracted into the top housing, but this is raised by a more convenient action than in the 35 MF; the flash simply rises under spring pressure when unlatched by pressing its top.
The camera uses two AA batteries.
