Abstract

A camera has an objective which can be moved from an extended, operative position to an inoperative position retracted into the camera housing for dimensional compactness. The objective is driven by a motor from one to the other of those two positions and moved by hand back in the other direction, or is motor driven in both directions. The motor employed is the film transport motor anyway present. The objective is coupled to and decoupled from the drive motor in dependence upon the setting of a manual selector, so that the objective not be driven at improper times, and is preferably coupled and decoupled in automatic response to the setting of a manual selector used to implement other camera functions, so that extension and/or retraction of the camera objective occur automatically as a logical incident to the other camera functions selected by the user.
