Patent ID: 7679838

Claim:
A zoom lens comprising: a first lens unit having a negative refractive power; and a second lens unit having a positive refractive power, wherein the first lens unit and the second lens unit are arranged in order from the object side to the image side, wherein the zoom lens performs zooming by changing a distance between the lens units, wherein the first lens unit includes a compound optical element including a lens element and a resin layer having optical characteristics different from optical characteristics of the lens element, the resin layer being laminated on the lens element, and wherein the following conditions are satisfied: 31<|ν dg−νdj| 26>νdj 0.10>|Δθ gFj| where νdg is an Abbe number of a material of the lens element, and νdj and ΔθgFj are an Abbe number and an anomalous partial dispersion ratio, respectively, of a material of the resin layer.
