Abstract: In the zoom lens, a first optical system is formed on the magnification side, and a second optical system is formed on the reduction side, with the intermediate image formed between the first optical system and the second optical system. The second optical system consists of, in order from the magnification side, a first lens group that has a positive power, a second lens group that has a positive power, a third lens group that has a positive or negative power, and a fourth lens group that has a positive power. During zooming, the second lens group and the third lens group are moved by changing spacings between the groups adjacent to each other in a direction of an optical axis, and the fourth lens group remains stationary with respect to the reduction side imaging plane.

Abstract: The present invention provides an imaging device and a focusing control method capable of performing reliability determination of a phase difference AF at high speed. A phase difference AF processing unit (19) performs a correlation operation with respect to detection signal groups in first pairs P1, and performs a correlation operation with respect to detection signal groups in second pairs P2. A system control unit (11) compares a difference between a first correlation amount M1 which is a minimum correlation amount between the detection signal groups in the first pairs P1, among obtained results of the correlation operation with respect to the first pairs P1 and a second correlation amount M2 which is a minimum correlation amount between the detection signal groups in the second pairs P2, among obtained results of the correlation operation with respect to the second pairs P2 with a threshold value TH, to thereby determine a reliability of a focusing control based on the phase difference AF method.

Abstract: A zoom lens forms an intermediate image at a position conjugate to a reduction side imaging plane and forms the intermediate image again on a magnification side imaging plane. The zoom lens includes a plurality of lens groups including at least two movable lens groups, which move by changing spacings between the groups adjacent to each other in a direction of an optical axis during zooming, at a position closer to the reduction side than the intermediate image. Among the plurality of lens groups, a final lens group closest to the reduction side has a positive refractive power, and remains stationary with respect to the reduction side imaging plane during zooming. The zoom lens satisfies predetermined conditional expressions (1) and (2) about the focal lengths of the movable lens groups.
