Carl Zeiss Vario SAL-2470Z

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 & 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.

  • 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.
