Abstract: An underwater single-use camera comprises a water-resistant casing, and a thumbwheel positioned outside the casing to be manually rotated in a film winding direction. The casing has a protective raised sealing lip disposed at a location which would cause the raised lip to obstruct one's finger when the finger is moved in contact with the thumbwheel to rotate the thumbwheel in the film winding direction, and it has a guide positioned adjacent the thumbwheel to direct the finger over the raised lip.

Abstract: In a photographic camera, a warning flag is supported for movement between a non-operative position outside the field of view of the camera viewfinder to prevent the warning flag from being seen in the field of view and an operative position a certain distance in front of the viewfinder to make the warning flag visible in the field of view. The viewfinder includes a magnifier lens located to place the warning flag in focus when the warning flag is in its operative position but to not substantially distort the view through the viewfinder of a subject to be photographed.

Abstract: A photographic camera comprises a camera housing with a viewfinder having a defined field of view, a hollow lens snout projecting from the camera housing forward of the viewfinder, a taking lens supported substantially at a front end of the lens snout, and exposure control means.
