PROBLEM TO BE SOLVED: To provide a compact camera constituted so that no parallax is caused and the focusing movement and the zooming movement of a photographing optical system are not restricted. SOLUTION: This camera is the lens shutter type single-lens reflex camera equipped with the zoom photographing optical system consisting of 1st to 4th lens groups 41a, 42a, 43a and 44a and a shutter unit 43c incorporating a shutter used also as a diaphragm. Besides, a pop-up movable system total reflection mirror 45a switching an optical path to the optical path of luminous flux for photographing or the optical path of luminous flux for a finder between the 2nd and 3rd lens groups 42a and 43a is provided near the front side of the unit 43c so as to be moved for zooming along optical axes AX and AX1 together with the unit 43c. |
