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 & 945 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.
