ZOOM LENS, OPTICAL DEVICE, AND METHOD FOR MANUFACTURING ZOOM LENS

摘要

PROBLEM TO BE SOLVED: To provide a zoom lens having an exit pupil position sufficiently far from an image surface and having excellent optical performance, an optical device, and a method for manufacturing the zoom lens.SOLUTION: A zoom lens includes, arranged in order from an object side: a first lens group G1 having positive refractive power; a second lens group G2 having negative refractive power; a third lens group G3 having positive refractive power; a fourth lens group G4 having negative refractive power; and a fifth lens group G5 having positive refractive power. The zoom lens zooms from a wide-angle end state to a telephoto end state by moving the first lens group G1, the second lens group G2, the third lens group G3, the fourth lens group G4, and the fifth lens group G5 along an optical axis so as to change a distance between the first lens group G1 and the second lens group G2, a distance between the second lend group G2 and the third lens group G3, a distance between the third lens group G3 and the fourth lens group G4, and a distance between the fourth lens group G4 and the fifth lens group G5. The zoom lens satisfies the following conditional expression (1): 2.30
