Abstract:
Provided is a zoom lens comprising, in order from an object side to an image side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, and a rear unit including at least one lens unit, in which the second lens unit is configured to move during zooming, an interval between each pair of adjacent lens units is changed during zooming, the rear unit has a positive refractive power over an entire zoom range, and the first lens unit includes a diffraction surface formed at a cemented surface of two optical elements cemented to each other. A focal length of the first lens unit, an amount of movement of the second lens unit during zooming from a wide angle end to a telephoto end and a back focus at the wide angle end are appropriately set.

Claim (Index 6):
A zoom lens according to  claim 1 ,\n wherein the first lens unit includes a plurality of positive lenses, and wherein the following conditional expression is satisfied:\n nd 1 p> 1.55, \n where nd 1 p  represents a minimum value among refractive indices of materials of the plurality of positive lenses.
