Abstract
A variable format camera comprising a front cover part having a particular-format viewfinder opening, and at least one other-format mask movable beneath the front cover part into alignment with the viewfinder opening to change the format of the view through the viewfinder opening to that of the mask and out of alignment with the viewfinder opening, is characterized in that a format-encodement-on-film switch is actuatable to provide a format encodement on a filmstrip in the camera; the mask has a switch actuator for actuating the encodement switch; and a rigid support for the switch actuator maintains a gap between the switch actuator and the encodement switch when the switch actuator does not actuate the encodement switch, to prevent the switch actuator from accidentally actuating the encodement switch because the front cover part is pressed inwardly.
