PROBLEM TO BE SOLVED: To constitute a focus detector having plural focus detection areas so that stray light is prevented from occurring with a simple constitution. SOLUTION: Plural lens parts 13a, 13b and 13c are arranged so that respective luminous flux R11 and R12 transmitted through plural visual field apertures 12X and 12Yb corresponding to the plural focus detection areas orthogonally cross between a condenser lens 13 and an image reforming optical system 15. Thus, a light shielding member (m11) for preventing a so-called stray light, that the luminous flux from some focus detection area is made incident on an undesired light receiving element column, from occurring, can be simplified. |
