ABSTRACT:
An automatic focus detection camera includes means for driving a photo-taking lens to obtain the in-focus state, operating means operated from an initial state to a first operating state and subsequently to a second operating state, and means for controlling the drive means so as to continuously effect the in-focus driving of the photo-taking lens, for example, for a predetermined time when the operating means is in the initial state. The control means further drives the photo-taking lens until the in-focus state is obtained when the operating means is operated to the first operating state, and controls the drive means so as to restrain the photo-taking lens at that position when the in-focus state is obtained.
