ABSTRACT:
Apparatus for exposure control/focus adjustment for a camera comprises an exposure controlling mechanism, a focus adjusting mechanism and a source of rotary drive. The drive from the source is transmitted through a differential gearing to the exposure controlling mechanism and the focus adjusting mechanism. The differential gearing is operated such that the transmission of the drive to either one of the exposure controlling mechanism and the focus adjusting mechanism is blocked while allowing the other mechanism to be driven.
