ABSTRACT:
A camera according to the present invention comprises: an indicator driving device which drives an indicator of a film cartridge so that the indicator indicates either a film-usable status or a film-unusable status; a film-feeding device; a discriminating function for discriminating whether the sensitivity of the loaded film is equal to that set for exposure calculation so as to output a matching signal when the former sensitivity is equal to the latter and to output a mismatching signal when the former differs from the latter; an instructing function for giving an instruction to rewind a partially-used film; and a control function for, at least on condition that the instruction is given, rewinding the film by the film-feeding device. The control function also controls the indicator driving device so that the indicator indicates the film-usable status when the matching signal is output and so that the indicator indicates the film-unusable status when the mismatching signal is output.
