<p>The present invention is a fire-group zoom lens (ZL) which has a first lens group (G1), which is disposed closest to the object, has a positive power, and comprises a prism (P) and a plurality of lenses disposed closer to the object than the prism (P), and the plurality of lens components include one positive lens (L12) that satisfies ½d > 50, where ½d is the Abbe number, with respect to the d-line.
The second lens group (G2) is negative; the third lens group (G3) is positive, at least part of which can move perpendicularly to the optical axis to correct image shake; the fourth lens group (G4) is positive; and the fifth lens group (G5) is negative.</p> |
