Lens apparatus and image capturing apparatus

摘要

A lens apparatus includes: an optical system which includes a movable lens group, the optical system including a first correction lens group which adjusts an optical performance of the optical system and a second correction lens group which adjusts a center position of an image which is formed by the optical system; and a control unit which controls driving of the first correction lens group so as to correct the change of the optical performance due to movement of the movable lens group based on position information of the movable lens group and controls driving of the second correction lens group so as to correct displacement of the center of an image due to the movement of the movable lens group and the first correction lens group based on position information of the first correction lens group.

1. A lens apparatus comprising:
an optical system which includes a movable lens group, the optical system including a first eccentricity/tilt correction lens group which adjusts an optical characteristic of the optical system by changing a position with respect to an optical axis and second camera-shake correction lens group which adjusts a center position of an image which is formed by the optical system by changing the position with respect to the optical axis in a plane perpendicular to the optical axis; and at least one central processing unit configured to execute a control unit configured to control the first eccentricity/tilt correction lens group so as to correct the change of the optical characteristic due to movement of the movable lens group based on position information of the movable lens group and configured to control driving of the second camera-shake correction lens group so as to correct displacement of the center of an image due to the movement of the first eccentricity/tilt correction lens group based on position information of the first eccentricity/tilt correction lens group.
