ABSTRACT:
A camera has a zoom lens which includes a variator and a compensator. However, in order to simplify the whole external form of the camera, reduce the size thereof, and further to materially eliminate the treatment of appearance of the taking lens, a linear movement means which includes a threaded shaft provided for linearlly moving a variator and a compensator composing a zoom lens and the nuts to be engaged with the threaded shaft and an electrically driving means for driving this linear movement means are covered by a housing of a camera body, a zoom operation key provided on this housing is caused to be operatively related to an electric circuit which drives and controls the motor.
