Abstract

PURPOSE:To prevent a shift between a distance measuring view field mark and an actual distance measuring range, by separating a finder optical system and a distance measuring optical system from the same optical path. CONSTITUTION:A finder optical axis 51 is matched with an object to be photographed, by a distance measuring view field mark 66 in the finder, a light source 55 is emitted of light, and when the object to be photographed is scanned by infrared rays, and reflected rays are reflected by a dichromic mirror 57, and are made incident to a photodetecting element 56 through a lens 54 and mirror 63. Also, a distance of the object to be photographed is detected from a turning angle theta and a base line distance D of a light source 55 in case when the incident light quantity has become maximum, and the automatic focus control is executed by moving a lens barrel 43 in the optical axis direction in accordance with a distance of the object to be photographed. In this way, the distance measuring view field mark in the finder, and an actual distance measuring range are not varied by a distance of the object to be photographed.
