ABSTRACT:
Disclosed is a camera including a camera housing and an objective lens having an image axis. The objective lens for the camera is mounted in a tube which is movable between an extended exposure position and a retracted storage position. When the tube is in the extended exposure position, an annulus around the tube cooperates with a projection on the tube to set the precise extended position necessary to provide a sharply focused image on the camera film.
