Abstract

A camera with a photographing optical system, including a focus adjusting system which captures images at different focal positions via an image pickup device while moving a focusing lens group within a controllable searching range, and moves the focusing lens group to the in-focus position; a memory which stores a first image captured when an in-focus state is achieved; and a comparing device which compares the first image stored in the memory with a second image captured via the image pickup device before commencement of movement of the focusing lens group. The focus adjusting system operates within a limited searching range including a current position of the focusing lens group when predetermined conditions are satisfied, including a condition upon which it is determined that the first image and the second image match each other completely or by a predetermined degree.
