PROBLEM TO BE SOLVED: To provide a camera capable of accurately detecting the focus in a wide range area of photographic image plane without vignetting focus detecting luminous flux even with respect to a photographing optical system dark in F value (having a large F value) in a camera equipped with a focus detector using a concave sub mirror. SOLUTION: A phase difference detection type focus detecting optical system (22) receives the focus detecting luminous flux (21a and 21b) through a concave mirror reflecting member (3) and a semitransparent reflection member (2). A correction optical system (16) arranged between the members (2) and (3) corrects deviation of the direction of the focus detecting luminous flux (21a and 21b) caused by the member (3) in accordance with image height at a focus detecting position. |
