(From Sony lens literature) The new Carl Zeiss Vario-Tessar T* 16-70mm F4 zoom lens gives photographers the opportunity to experience legendary Carl Zeiss optical excellence in a supremely compact, easy-to-carry zoom lens. A practical 4x zoom range of 16-70mm (24-105mm in 35mm full-frame equivalent) makes this model ideal for a wide range of everyday photo situations, from landscapes and portraits to informal snapshots and everything in between.
This premium lens provides outstanding contrast and resolution at all zoom settings, and it has a renowned T* coating on optical surfaces that reduces glare and ghosting for natural color reproduction, superb definition and clarity. Lens size and weight are minimized thanks to Advanced Aspherical lens (AA lens) technology, which combines four aspherical elements with one ED glass element.
Additionally, the new Carl Zeiss E-mount lens maintains a constant F4 maximum aperture at all focal lengths, reducing the need for high ISO settings when zoomed in and allowing the use of high shutter speeds to freeze fast-moving action. It also has an extra refinement in the circular aperture which enables naturally smooth background defocus, and features Optical SteadyShot image stabilization for reducing the effects of hand shake.
Aesthetically, it has a stylish metal exterior and the premium look, feel and construction expected from Carl Zeiss.
