A camera comprising a door moveable to be closed, a sprocket wheel having respective teeth for entering successive spaced perforations in a filmstrip to engage the filmstrip and being moveable to a film engaging position for one of the teeth to enter one of the film perforations, and an actuator moveable to move the sprocket wheel to its film engaging position when the door is moved to be closed, is characterized in that the actuator has a compliant member which yields elastically when the actuator is moved to move the sprocket wheel to its film engaging position, but one of the teeth comes to rest against a limited section of the filmstrip between two of the film perforations rather than the tooth entering one of the perforations, whereby the compliant member acts to prevent the tooth from perforating the limited section of the filmstrip.
