The ultimate all-in-one zoom lens designed specifically for DSLR imaging. It’s the first professional-grade 5X zoom lens specifically designed for APS-size CCD image sensors -- providing incredible precision in a single compact, easy-to-carry lens that carries you from 24mm wide-angle to 120mm telephoto (35mm equivalent). Advanced Carl Zeiss® optical design and anti-flare T* Coating make this one of the most valued lenses in the world of digital photography.
Feature List
5X Zoom Range:
Smaller and lighter, it’s the only 5X zoom lens designed specifically for the APS-size CCD imager used in the Sony® α (alpha) DSLR-A100 camera.

Glass-Molded Aspherical Lens Elements:
Two glass-molded aspherical lens elements correct visual aberrations and improve picture quality across the entire zoom range.

Circular Aperture:
Because aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.

Auto Clutch:
In auto-focus mode, the manual focus ring does not rotate -- and in manual focusing, a wider focus ring provides a solid, hands-on feel.
