This fast wide-angle zoom lens gives demanding photographers exceptional design options with extreme image angles, particularly if both digital and analog full-format cameras are used. Digital APS-C cameras offer a zoom range from a moderate wide angle to the standard focal length.
When slightly stopped down, the lens achieves special, uniformly high image quality and illumination over the entire image field. The integrated ultrasound motor (SSM) allows the Vario-Sonnar to focus extremely fast and almost without any noise(1). The Vario-Sonnar T* 2.8/16-35 ZA SSM II does not change its length during zooming, and its fixed filter thread enables the convenient use of polarization filters.
The sturdy mount, interior focusing, front bayonet for the lens shade and the metal filter thread make this lens ideal for professional photography.
(1) Autofocus available only in conjunction with camera models that support SSM (e.g. Konica Minolta cameras made after 2001 and all Sony Alpha models)

The new Mark II lenses feature many new improvements compared to their predecessors: they impress primarily with optimized stray light-reducing measures which minimize ghost images and reflections – particularly in critical lighting situations. Furthermore, they are equipped with new dust and moisture-resistant mounts that reliably protect the optics and mechanical parts even in adverse weather conditions. The autofocus system on the SSM system (supersonic wave motor) was also optimized. This increases not only the AF speed, but also the precision compared to the Mark I lenses.
Design of the autofocus system requires extremely accurate shifting of particular lens groups. While this is normally achieved via mechanical coupling from the camera body, ZA lenses feature a built-in SSM (Super Sonic wave Motor) focusing system for even more refined AF performance.
The optical elements of ZEISS lenses feature T*® anti-reflective coating on all surfaces and an optical design that guarantees images of superior brilliance at all times, even in unfavourable lighting conditions. We apply the anti-reflective coating to the lens surfaces by the vapour deposition of extremely thin, transparent layers on the glass. In this process, special substances are vaporized with extremely high energy in a high-vacuum environment and are subsequently deposited on the glass surfaces, one after another, as layers with precisely controlled thicknesses to achieve the desired reduction of reflective properties. The first coating techniques were employed by ZEISS as long ago as in the 1930s.
Rich, vibrant colors are vital to creating a lasting impression. Stray light in the lens, however, would lead to a brightening of the image, which is particularly visible in shadow areas. Image contrast is lowered; the image appears dull and bleached. We combine various, elaborate techniques to reduce unwanted stray light.
