ABSTRACT:
A film-size-interchangeable sheet film holder for a camera using a large-sized film holder for accommodating sheet films has a structure which allows use of a small-sized film holder for smaller films without requiring replacement of a rear camera frame (containing a focusing glass, etc.) for attaching the holder, as in the prior art. The film-size-interchangeable sheet film holder includes a larger film holder in the form of a relatively wide plate having a groove in which a smaller film holder can be accommodated, the smaller film holder being secured onto the larger film holder by plate springs.
