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 (equivalent to 36-105mm in 35mm format terms).

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 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-24-70mm 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.
