Abstract:
Provided is a zoom lens including, in order from an object side to an image side: a first lens unit having a negative refractive power and configured not to move for zooming; a second lens unit having a positive refractive power and configured to move to an object side for zooming from a wide angle end to a telephoto end; and a rear lens unit arranged closest to the image side, wherein the rear lens unit includes an optical element having a positive refractive power and cemented with a lens made of a glass material, and wherein the optical element satisfies the following conditions: −2.100×10 −3 ×νdm +0.693<θ gFm ; and 0.555<θ gFm <0.900, where νdm and θgFm are expressed by the following expressions: ν dm =( Nd −1)/( NF−NC ); and θ gFm =( Ng−NF )/( NF−NC ), where Ng, NF, Nd and NC respectively represent refractive indices with respect to a g-line, an F-line, a d-line, and C-line.

Claim (Index 6):
The zoom lens according to  claim 1 , wherein the first lens unit includes a lens unit configured to move for focus adjustment.
