The present invention provides a camera for selectively supporting a film having perforations along its upper and lower edges and a film not having the perforations, comprising masking plates for photographic screen size setting that are installed in a camera body to be freely movable to positions at least between the inside and outside of perforations, a perforation detector for determining whether perforations are present on the edges of at least the photographic screens of a film loaded in a camera body, and a masking plate drive for receiving an output of the perforation detector, moving the masking plates to a screen size setting inside of perforations when a film is perforated, and moving the masking plates to a screen size setting including a portion corresponding to the perforations when a film is imperforated.
