LENS CAP

摘要

A lens cap assembly includes a hood device, a connecting ring and a ferrule device. The connecting ring is used to rotationally connect the hood device to a barrel of a lens assembly. The ferrule device is movable between a shrunk position and an expanded position. In the shrunk position, the ferrule device prevents the hood device from rotation on the barrel. In the expanded position, the ferrule device allows the rotation of the hood device on the barrel.
