Abstract
The lens apparatus comprises a second lens barrel configured to hold a lens, a first guide bar configured to guide the second lens barrel in an optical axis direction, a bar holding member that holds one end side of the first guide bar, a cam follower engaged with the bar holding member and including a portion eccentric with respect to a rotation axis, and a first fixing member configured to hold the bar holding member via the cam follower. A position on of the one end side of the first guide bar in a plane perpendicular to the optical axis is adjustable by rotating the cam follower with respect to the fixing member from a direction orthogonal to a direction along the optical axis of the lens.
