Abstract
A lens apparatus having a focus lens can be detachably attached to an imaging apparatus. A sensor of the imaging apparatus photoelectrically converts an optical image formed via the lens apparatus. A generation unit generates an image based on an image signal output from the imaging apparatus. The imaging apparatus receives information about a focal length variation from the lens apparatus received by a lens communication control unit configured to control communication with the lens apparatus, and an image magnification variation correction control unit corrects the magnification of the image based on the information.
