The SAL-2470Z Carl Zeiss Vario-Sonnar f2.8 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). Features include a SSM (Super Sonic wave Motor) designed 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.Features:Compact design, all around versatilitySuperior large-aperture performanceIn-camera image stablizationSuper sonic wave motorCarl Zeiss T* coatingMulti-element designGlass-molded aspherical lens elementsExtra-low Dispersion glassIncludes:Front and rear lens capsSH0005 petal lens hoodLens carrying case
