Abstract:
Provided is a zoom lens including in order from an object side: a positive first unit configured not to move for zooming; a negative second unit configured to move for zooming; a positive third unit configured to move for zooming; a negative fourth unit configured to move for zooming; and a positive rear unit including at least one lens unit, wherein the fourth unit is configured to move for focusing, and wherein a focal length of the fourth unit, a focal length of the rear unit at a telephoto end, a focal length of the zoom lens at a wide angle end, amounts of movement of the second and third units from the wide angle end to the telephoto end, a half angle of view at the wide angle end, an amount of displacement of an in-focus position.

Claim (Index 7):
A zoom lens according to  claim 1 , wherein a conditional expression\n 0.99< Nd 1 pr/Nd 1 pf< 1.40 is satisfied, where Nd1pr represents a refractive index of a positive lens G1pr arranged closest to the image side in the first lens unit, and Nd1pf represents an average of refractive indices of positive lenses other than the positive lens G1pr in the first lens unit.
