Abstract: An autofocus camera conducts a focus detection operation with one of differently directed sets of photoelectric conversion elements which is given priority according to the detected attitude of the camera. If focusing cannot be effected using the elements given priority, a focus detection operation is automatically conducted with the other elements. Also provided is a camera having a first mode of operation in which focusing detecting operations are conducted which collectively utilize outputs of all of the elements of differently directed sets of photoelectric conversion elements when a first camera attitude is detected, and a second mode of operation in which focusing detecting operations are conducted which collectively disregard the output of at least one conversion element when a second camera attitude is detected.

Abstract: A recording apparatus for a camera using a photographic film bearing a magnetic recording medium comprises a magnetic head capable of assuming a recording position with the magnetic head pressed to the film and a retracted position with the magnetic head away from the film. When the magnetic head is at the recording position, a reference pin engages an edge of the film. To move the magnetic head to the retracted position, a drive mechanism moves the magnetic head in a direction along the film width, thereby disengaging the reference pin from the edge of the film, and then moves the magnetic head in a direction away from the film plane.
