Sony 24-70mm f/2.8 Carl Zeiss Vario Sonnar T Zoom Lens for Sony Alpha DSLR Cameras

Introducing the High-Performance Carl Zeiss Large-Aperture Zoom Lens

The SAL-2470Z Carl Zeiss Vario-Sonnar f2.8 24-70mm Zoom Lens is a remarkable all-around performer. Equipped with an SSM (Super Sonic wave Motor) design, it delivers fast and silent autofocus. The pro-quality Carl Zeiss T-coated optics effectively reduce lens flare, while the 17-element design, featuring two aspherical and two ED glass lens elements, minimizes distortion and virtually eliminates chromatic aberration.

Benefiting from the built-in Super SteadyShot image stabilization in every Sony α system DSLR, this lens offers a versatile wide-angle to medium telephoto range (35mm equivalent: 36-105mm) in a compact, lightweight package, making it ideal for a wide range of shooting applications.

Brilliant Performance in a Compact Design The superb Carl Zeiss Vario-Sonnar T* Zoom Lens provides large-aperture f2.8 brilliance, a 24-70mm all-purpose zoom range, and fast, silent autofocus with the SSM design. The aspherical and ED glass elements further enhance the lens's performance by reducing distortion for superior clarity and color (35mm equivalent: 36-105mm).

Exceptional Bokeh Effect When changing the aperture to defocus the background, the light sources appear blurred. This "bokeh" effect can be enhanced by the circular aperture blades used in this lens. Unlike conventional aperture blades with flat sides that create unappealing polygonal shapes, the α lenses maintain a near-perfect circular aperture, resulting in smoother, more natural defocusing.

Advanced Optics for Superior Image Quality As focal lengths get longer, conventional optical glass lenses often struggle with chromatic aberration, leading to lower contrast, color quality, and resolution. However, the ED glass in this lens dramatically reduces chromatic aberration at telephoto ranges, providing superior contrast across the entire image, even at large aperture settings.

Furthermore, the aspherical lens design dramatically reduces spherical aberration while also reducing the lens size and weight. Specially shaped "aspherical" elements near the diaphragm restore the alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture.

Precision Coatings for Outstanding Image Quality Pioneered by Carl Zeiss, the T* (T-Star) coating on this lens virtually eliminates lens flare, internal reflection, and light scattering that can degrade image quality. This coating ensures outstanding contrast and uniformly excellent resolution from edge to edge.

Versatile Lens Features The lens barrel features a button that, once focus is adjusted, can lock the lens at that focusing distance. This button can also be customized to serve as a preview function through the camera's settings.

The distance encoder is an integral component that contributes to the lens's ADI flash metering, delivering high-precision flash metering unaffected by the reflectance of subjects or backgrounds.

The SSM (Super Sonic wave Motor) technology ensures smooth and silent autofocus operation, with immediate start and stop responses, and improved overall AF precision.
