High-performance Carl Zeiss® large-aperture zoom. The SAL-2470Z Carl Zeiss® Vario-Sonnar® f2.8 24-70mm Zoom Lens is a brilliant all-around performer—with SSM (Super Sonic wave Motor) design for fast, silent auto-focus, pro-quality Carl Zeiss® T* coated optics to reduce lens flare, and 17-element design with two aspherical and two ED glass lens elements to minimize distortion and virtually eliminate chromatic aberration. It also benefits from the Super SteadyShot® image stabilization built into every Sony ? system DSLR—and its wide-angle to medium telephoto range and compact, lightweight design is ideal for a wide range of shooting applications (35mm equivalent: 36-105mm).
Compact Design, All-Around 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).
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.
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 α system DSLR -- and enabling accessory lenses to eliminate the extra weight and expense of in-lens stabilization mechanisms.
SSM (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.
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.
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.
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.
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.
