Abstract: A lens apparatus includes: a correction unit moving perpendicularly to an optical axis and including a correction optical system correcting an image blur; a driving unit driving the correction unit; an engaging unit movable between an engaging position where the engaging unit abuts abutting portions of the correction unit to engage the correction unit and a non-engaging position where the engaging unit makes the correction unit movable; a biasing unit biasing the engaging unit from non-engaging position to engaging position; and a non-engaging position maintaining unit maintaining the engaging unit at non-engaging position by being engaged with the engaging unit, wherein the correction unit moves to press the non-engaging position maintaining unit beyond a range driven by the driving unit during image-blur correction to disengage the non-engaging position maintaining unit and the engaging unit, and the biasing unit moves the engaging unit from non-engaging position to engaging position.

Abstract: A lens barrel includes a holder configured to hold a lens, a fixing unit configured to fix the holder, an intermediate unit arranged between the fixing unit and the holder, a first fixing member configured to fix the intermediate unit and the holder, a second fixing member configured to fix the fixing unit and the intermediate unit, a first tilter configured to tilt an optical axis of the lens around a first straight line that is unparallel to the optical axis of the lens, by changing a tilt of the holder relative to the intermediate unit, and a second tilter configured to tilt the optical axis of the lens around a second straight line that is unparallel to the optical axis of the lens and the first straight line, by changing a tilt of the intermediate unit relative to the fixing unit.
