ABSTRACT:
A lens apparatus includes a barrel and a focus member mounted on the barrel. The barrel includes a fixing body and an engaging unit disposed at an outside wall of the fixing body. The focus member includes a retaining body contacted with the outside wall of the fixing body and a retaining unit disposed at an inside wall of the retaining body. The retaining unit and the engaging unit fasten each other for mounting the focus member on the barrel. When a force is applied on the focus member, the focus member drives the barrel to rotate by a friction generated between the retaining unit and the engaging unit.
