Abstract
A lens apparatus including a focus lens is attachable to and detachable from an image capturing apparatus. An image sensor photoelectrically converts an optical image formed through the lens apparatus. An image generation unit generates an image based on an image signal output from the image capturing apparatus. An image magnification variation correction control unit receives information about a variation in focal length from the lens apparatus by a lens communication control unit configured to control communication with the lens apparatus, and the image magnification variation correction control unit corrects a magnification of the image based on the received information.
