A camera with an optical system and having a visual axis detection device includes observing structure for observing an object, and circuitry for detecting a visual axis of an observer looking into the observing structure. Circuitry is provided for detecting a focus condition of each of a plurality of different positions in a photographing field of view, and for outputting a plurality of focus signals respectively corresponding to the plurality of detected focus conditions. Circuitry is also provided for obtaining a focus result from a focus signal which corresponds to the position in the field of view looked at by observer as detected by the detecting circuitry. Circuitry is also provided for preparing a focus adjustment signal based on the focus result obtained by the obtaining circuitry. Finally, prohibition circuitry is provided for preparing a prohibit signal to prohibit a focus adjustment operation of the optical system, the prohibit signal being based on an output from either one of the circuitry for detecting the direction of the visual axis and the circuitry for detecting the focus condition.
