PURPOSE:To set a close photographing mode through one action without complicated operation and to realize macro photographing performed more closely than the close limit of the conventional lens as for a back focusing control system autofocusing single lens reflex camera. CONSTITUTION:When a macro button(close photographing button) 27 is operated in a state where a mode is switched to an MF mode, an AF control circuit 20 controls an AF motor driving circuit 21 to drive a driving motor 7a to adjust so that a distance between the lens mount 1 of a front block of a camera main body and the aperture surface of a rear block may be maximum. Then, the effect is displayed on a macro photographing warning display part 28. A photographer can perform close-up in an instant, and the close-up performed much more closely is realized by operating the distance ring of a lens. |
