A. The film back consists of a film holder and a film back frame, with
exclusive film backs available for 120 and 220 roll films. The film hold-
er has an insert or frame for loading film, as well as a built-in winding
mechanism.
B. The film back frame has a base with a dark slide slit and a back
cover with an ASA/ISO film dial and a film type indicator frame. The
film back frame completely encloses the film holder and shields it
from outside light, as well as connecting it to the main camera body
and also coupling with the finders with built-in exposure meters.
A. To open the back cover, squeeze the left and right back cover
release buttons, in the arrow-indicated directions, at the same time

the back cover.
