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 retractive storage position. When the tube is in the extended exposure position, a locking device responsive to operation of the shutter release, increases the biasing force on the objective lens towards its extended position. The locking device is made up of several cams spring biased against two pins radially projecting from the objective tube. The cams are prevented from bearing against the pins by a control linkage which prevention is released during shutter actuation.
