A lens apparatus includes a fixed barrel, a first optical element, a rotary barrel configured to be rotated relative to the fixed barrel about an optical axis of the first optical element and move the first optical element; a contact member including rolling members respectively arranged at positions about the optical axis. The rolling members are in contact with the rotary barrel. The contact member is restricted in rotation relative to the fixed barrel about the optical axis. A pressing member presses the contact member toward the rotary barrel. A second optical element is different from the first optical element. An operation member is configured to be rotated relative to the fixed barrel about the optical axis and move the second optical element. A space, through which the operation member passes, is formed between two of the rolling elements in a circumference of the contact member.
