Abstract
An extended film magazine for an underwater camera is adapted to be attached to the camera in place of the rear door by a bezel means which provides watertight attachment between a housing of the magazine and the camera. The bezel means aligns and holds a first film holding cassette and a film take-up assembly having all of the operating components thereof, in the housing for easy access and loading. The bezel means also includes sealing means to effectively seal the magazine housing and the camera, and the film take-up assembly is mechanically coupled to the existing film transport mechanism of the camera to drive a take-up means held in this take-up assembly to move unexposed film from the film cassette, through the camera and onto the take-up means. The take-up assembly mechanically coupled to the existing film transport of the camera also includes a mechanical take-up drive and a counter means to measure the length of the film passed through the film transport, together with a light source to illuminate the counter so as to enable it to be read underwater, through a lens means in the housing.
