The lens apparatus which includes a lens system, a cam barrel including a cam surface, and a moving barrel provided with a cam follower in contact with the cam surface and configured to be moved in a direction of an optical axis of the lens system by rotation of the cam barrel around the optical axis. The cam surface is parallel to a direction orthogonal to the optical axis. The cam barrel includes a tapered surface inclining with respect to the direction orthogonal to the optical axis. The moving barrel is provided with a tapered follower in contact with the tapered surface and a pressing mechanism configured to bias the tapered follower in the direction orthogonal to the optical axis so as to press the tapered follower against the tapered surface to thereby press the cam follower against the cam surface in the direction of the optical axis.
