(From Sony lens literature) The new Carl Zeiss Vario-Tessar T* 24-70mm F4 lens combines a versatile 24-70mm focal length with a useful F4 maximum aperture at all focal lengths, making it an ideal lens for portraits, landscapes and every day shooting. The new lens also features Optical SteadyShot® for keeping shots crisp and clear at all focal lengths, even at slower shutter speeds. The SEL2470Z is designed with five aspherical elements with one ED glass element, assuring images are highly detailed and accurate. Unique to Carl Zeiss, it also features T* coating on optical surface which cuts glare and internal reflections to boost contrast. Critical areas of the lens exterior feature dust and moisture resistant seals that help to ensure professional reliability even in tough environmental conditions.
