A compact, lightweight standard zoom lens with superior optical performance plus a built-in Image Stabilizer. The IS system reduces the possibility of blurred photographs caused by camera shake, enabling hand-held photography in comparatively dim light without a flash or tripod. The IS system is composed of a pair of gyro sensors to detect vertical and horizontal motion and a microprocessor that compensates for it by shifting special IS lens elements in parallel with the perceived movement. At the wide-angle end of the zoom range, the equivalent shutter speed gain is approximately 1.5 stops while at the telephoto end, it is approximately 2 stops. In addition, the lens has a USM drive mechanism for optimum AF performance, and the pulse control diaphragm (EMD) ensures precise aperture control.

Bring your subjects closer. Shoot beautiful scenery, action-packed sporting events and detailed close-ups with this wide-angle telephoto lens. Get into the action. Designed to take advantage of APS-size CCD imagers like the Exmor sensor of the Sony a(alpha) DSLR-A700 camera, this amazingly compact premium zoom lens provides superior all-around performance. Its 35mm-equivalent range of 24mm wide-angle to 157.5mm telephoto is perfect for capturing faraway subjects, sports events, dramatic landscapes and intimate close-ups. Internal Focusing System – Internal lens elements move, so the overall length does not change — creating a lens that focuses more quickly and doesn’t alter its balance. Sophisticated Multi-Element Design – 16 lens elements in 13 groups correct visual aberrations across the entire zoom range and help reduce weight. ED (Extra-low Dispersion) Glass – ED Glass lens elements minimize flare and greatly reduce chromatic aberration, giving you sharp, clear shots even at full telephoto extension. 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.
