摘要 A lens apparatus includes an imaging optical system including a movable lens unit, a drive unit configured to drive the movable lens unit, and a control unit configured to cause the movable lens unit to perform a wobbling motion in an optical axis direction by alternatively outputting to the drive unit a first drive command for driving the movable lens unit at a first driving speed and a stop command for stopping driving of the movable lens unit, and to move the movable lens unit based on contrast information obtained from an image pickup unit during the wobbling motion of the movable lens unit, wherein, at least one of before and after outputting the first drive command to the drive unit, the control unit outputs to the drive unit a second drive command for driving the movable lens unit at a second driving speed lower than the first driving speed.
