The Sony SAL-2470Z 24-70mm f/2.8 Carl Zeiss Vario-Sonnar T* Lens is a professional-grade bright zoom lens specifically designed for the Sony Alpha SLR series. It follows a compact, lightweight design and offers a wide-angle to medium telephoto range, which makes it ideal for a wide range of shooting applications.

Carl Zeiss' optical design and anti-flare T* coatings used for this lens help to reduce flare and to increase contrast. When used with a digital SLR camera, the equivalent focal length for this lens is 36-105mm. It is a compact all-in-one lens, and is ideal for snapshots, portraits, interiors or outdoor scenery.

• Versatility

This superb 24-70mm zoom lens is an excellent choice for a wide range of photo applications...a lens you can put on and leave on, providing large-aperture brightness that's easy to carry (35mm equivalent: 36-105mm).

• Super Sonic Wave Motor

Designed for fast, smooth, silent automatic focusing, this unique technology achieves high torque at low speed with rapid start/stop response. It operates through the ability of a piezoelectric device to reshape itself quickly when voltage is applied.

• Glass -Molded Aspherical Lens Elements

These precision lens elements correct distortion for sharper, more visually accurate images across the entire zoom range of the lens.

• Superior Large-Aperture Performance

Like other large-aperture Carl Zeiss lens designs, this f2.8 24-70mm zoom lens is simply magnificent in its ability to capture brilliant high-resolution images in low-light conditions requiring fully open aperture.

• Carl Zeiss T* Coating

Coated optics were pioneered by Carl Zeiss...and this superb lens features T* (T-Star) coating that virtually eliminates the lens flare, internal reflection and light scattering that can otherwise occur at glass-to-air surfaces.

• ED (Extra-low Dispersion) Glass

Because light of different wavelength (or color) bends at different angles when it passes through a lens, ED (Extra-low Dispersion) Glass is used in Carl Zeiss lenses to eliminate chromatic aberration by correcting certain wavelengths of light for sharp, clear images with well defined colors.

• In-Camera Image Stabilization

A major reason for its compact, lightweight design is the benefit of Super SteadyShot in-camera image stabilization, built into every Sony & 945 system DSLR...and enabling accessory lenses to eliminate the extra weight and expense of in-lens stabilization mechanisms.

• Multi-Element Design

The SAL-2470Z is designed with 17 lens elements in 13 groups, including 2 aspherical elements and 2 ED glass elements. Floating motion between the third and fourth groups of lens elements helps compensate for any aberrations caused by the zooming action of the lens.
