ABSTRACT:
A multiple point focus detection camera capable of acquiring focus detection data on objects within a photographer's field of vision is operable in an automatic or a manual mode, and can be automatically switched to the automatic or manual modes as a default upon the occurrence of certain events in order to reduce the likelihood of errors during photography. Automatic operation can be enabled (i.e., is the default) upon power-up or changing of lenses. Manual operation can be enabled when lens data indicates that a lens used most often by a professional photographer is in use. Either mode (automatic or manual) can be set as a default mode, which can be selected when the camera is placed in a self timer mode. A default mode change feature can be provided to allow a user to select automatic or manual as the default mode.
