Rear-focus zoom lens device and video camera

摘要

A rear-focus zoom lens device includes a wide-angle direction rotation restricting unit and a telephoto direction rotation restricting unit for separately restricting rotations of a zoom ring in a wide-angle direction and a telephoto direction and for separately canceling the restricting operations at any rotational positions of the zoom ring in the wide-angle direction and the telephoto direction, respectively, when rotating the zoom ring in the wide-angle direction and the telephoto direction, respectively.
