Abstract
A lens apparatus includes a first holder holding a first lens unit and moving, manually or by an external driver, in an optical axis direction, a second holder holding a second lens unit and being electrically driven in the direction, a transmission member supported by the second holder to be movable in a first range in the direction relative to the second holder, a driving unit moving the second holder in the direction via the transmission member, a biasing member biasing the transmission member toward an end of the first range opposite to the first lens unit, and a controller controlling the driving unit. Movable ranges of the first and second holders in the direction overlap each other. The controller determines a relative position between the driving unit and the second holder in the direction, and changes a control of the driving unit based on the relative position.
