Abstract:
1. A lens apparatus comprising: a correction unit movable in a direction perpendicular to an optical axis and comprises a correction optical system that corrects an image blur; a driving unit that drives the correction unit within a driving range at a time of image-blur correction; an engaging unit movable between a first position at which the engaging unit abuts abutting portions of the correction unit to engage the correction unit and a second position at which the engaging unit causes the correction unit to be movable; a biasing unit that biases the engaging unit toward the first position from the second position; and a stopper configured to engage the engaging unit to prevent the engaging unit from moving from the second position to the first position by the biasing unit, wherein the correction unit is configured to move beyond the driving range and press the stopper to disengage the stopper from the engaging unit so that the biasing unit causes the engaging unit to move from the second position to the first position, wherein the movement of the correction unit in the direction pressing the stopper is caused by gravity acting on the correction unit, when the driving unit stops driving the correction unit, and wherein the movement of the correction unit in the direction pressing the stopper causes the stopper and the engaging unit to be disengaged from each other.
