A lens apparatus capable of carrying out a suitable AF control operation even when text or character information is superimposed on a video signal is provided. The lens apparatus is configured to generate first and second AF evaluation values from a video signal obtained from an imaging unit of a camera apparatus, and to perform focusing control based on the second AF evaluation value. In the lens apparatus, the first AF evaluation value is selectively output to a second AF evaluation value generating unit for every scanning line of the video signal.
