摘要
A focus detection apparatus comprising a focus detection unit adapted to employ a photoelectric conversion element to detect a relative positional relationship between a pair of object images corresponding to a focus detection field; and wherein the focus detection unit are switchable between a first mode of operation in which such an object image corresponding to a focus detection field is detected by using a first number of areas of the photoelectric conversion element, and a second mode of operation in which such an object image corresponding to a focus detection field is detected by using a second number of areas of the photoelectric conversion element, different from the first number.
