影可能なズームレンズ構体。In a zoom lens that performs macro photography by displacing a correction lens of a zoom optical system, a holding cylinder of the correction lens and a correction system moving ring are linearly guided and connected to each other, and the holding cylinder is moved along the correction system moving ring during zoom operation. A macro switching ring and a macro feeding member integrated therewith are provided independently of the zoom ring which is moved integrally with the macro switching ring, and when the macro switching ring is operated, the macro feeding member moves only the holding cylinder in the optical axis direction. A zoom lens structure capable of extremely close-up photography, characterized in that it is configured to be able to be displaced.
