<p>PROBLEM TO BE SOLVED: To make a single lens reflex camera releasable at any time when a mirror-up photographing mode is set by simplifying the operation to switch a normal photographing mode to the mirror-up photographing mode and vice versa. SOLUTION: Mirror-up operation and stop-down operation in the mirror-up photographing mode are realized only with the shutter button 10 of an accessory 9 attached to the camera, and the operation to take a photograph by opening the shutter in the mirror-up photographing mode is realized by either the shutter button 10 of the accessory 9 or the shutter button 5 of a camera main body 1. Thus, even when a user wants to take the photograph promptly in the midst of the mirror-up operation, he (she) has only to operate the shutter button 5 of the camera main body 1 in the same manner as in the conventional camera, and can take the photograph without hesitation by the same operation feeling as in the conventional camera, thereby, he (she) does not lose a shutter chance.</p> |
