Abstract
An auto focus (AF) adjusting apparatus and a camera system of a lens replaceable camera are disclosed. AF is performed by correcting a location error of a focus lens due to a difference between a frequency band for performing AF detection and a frequency band for determining an improved location of an image surface of an imaging lens, and/or a target region for detecting a focal point.
