補正光学素子の作動機構。 A zoom lens capable of macro photography; A distance measuring device based on the triangular distance measuring principle that includes a light emitting part and a light receiving part; A short distance correction optical element that can move forward and backward in front of the light receiving part of this range finding device; A zoom lens In a zoom lens camera equipped with a cam ring helicoidally coupled to a fixed barrel, which transitions between a normal shooting range and a macro shooting range, the short-distance correction optical element is linked to the helicoidal peak of the cam ring, and the cam The ring retracts the correction optical element from the front of the light receiving section of the range finder when the zoom lens is positioned in the normal shooting range, and moves the correction optical element in front of the light receiving part when the zoom lens is positioned in the macro shooting range. An operating mechanism for a short-distance correction optical element of a lens shutter type zoom lens camera, which is characterized in that it can be moved forward.
