Zeiss Touit F2.8 12mm E-Mount - Sony
As far as the eye can see
With an angle of view of 99 degrees, the Touit 2.8/12 wide-angle lens will soon become a firm favourite, particularly for landscapes and architectural photography. Its unique T* multicoating guarantees maximum transmission and outstanding absorption of extraneous light. The result: breathtaking image quality from edge to edge and corner to corner of the entire image field. What’s more, all moving parts of the Touit 2.8/12, conceived specifically for Sony NEX and Fujifilm X Series cameras, are engineered for extreme precision and a long working life. And finally, its strong and rigid metal bayonet mount makes it an absolutely dependable companion for many years to come.
Features
Innovative product design
Innovative product design to ensure superior handling and fulfil the most stringent aesthetic expectations. ZEISS lenses are among the winners of the several thousand products entered for prominent design awards. The unmistakeable new product design is based on an integrative concept and focuses on essential functional elements. Even the lens hood, typically an accessory, is seamlessly integrated into the overall design. The metal bayonet mount guarantees extreme rigidity and rubberised setting rings enable precise manual control when needed. Flush-fitting, satinised surfaces visualise the optical and mechanical precision of each lens.
Full compatibility
The ZEISS Touit lenses are designed and constructed specifically for use on Sony NEX and FUJIFILM X Series cameras with APS-C sensors. The lenses are therefore fully-compatible and support all camera functions, including autofocus.
Ideal aperture characteristics
Photographers want to lead the viewer through their images. Planes with minimum depth of focus are often employed as creative elements. For instance, the background is kept intentionally out of focus to lead the viewer’s eye to the actual subject of the image. The Touit lenses feature a nine-blade iris that closes to create an almost perfectly circular aperture. The effect of this is the creation of a particularly harmonious effect in the out of focus areas of the image (‘Bokeh’).
Smooth and reliable AF action
The design of the autofocus system demands an extremely precise movement of certain lens elements. As the mass of the elements or groups to be moved within the optical system differs, various motor types may be installed. The focusing system of the Touit lenses is designed to guarantee robust and smooth autofocusing without any need for compromises or limitations in their optical design.
¨Information: To reach the best compatibility on Sony NEX Cameras (AF in video mode) we highly recommend to use the latest Sony NEX firmware.
Carl Zeiss T* anti-reflective coating
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 Carl Zeiss as long ago as in the 1930s.
