Single Exposure Attachment
By using the single exposure attachment provided, single
exposures can be made of dry plates (2 1/2 x 3 1/2 in.,
6.5x9cm) or cut films (4 3/4 x 6 1/2 in. cut film divided
into four 1/4 sizes or 2 1/2 x 3 1/2 in.) When using 4
3/4 x 6 1/2 in. cut film divided into four one-quarter sizes,
use a J-type film sheath. When using 2 1/2 x 3 1/2 in.
film, use a D-type film sheath.
Installing Method
Replace the camera back cover with the exclusive back
cover for single exposure. Always remove the spool in the
camera. Install a holder containing a dry plate or cut film
on the exclusive back cover, closing the outer frame of the
back cover to complete preparation.
PRECAUTION
Since the position of its focusing surface differs, the
conventional single exposure attachment for the MAMlYA C
series cannot be utilized on this camera.
