Abstract
An automatic-focus camera has a focus lock system that stores focus adjusting information so that a photo-taking lens may be kept focused on an object during one or more exposures. The camera has a self timer, an automatic exposure system with different program modes, and has continuous as well as single-frame operating modes. The focus lock system, which has different focus lock modes, influences the manner in which various operations of the camera are performed.
