For optimum compatibility of Touit lenses on Sony NEX cameras we recommend to use the latest firmware (1.02 for NEX-5R/NEX-6 and 1.03 for NEX-7 or higher). The firmware can be downloaded from the Sony website:

ZEISS Touit 2.8/12

As far as the eye can see

With an angle of view of 99 degrees, the ZEISS Touit® 2.8/12 wide-angle lens will soon become a firm favourite, particularly for landscapes and architectural photography. Its unique ZEISS 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 ZEISS 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.

Distagon Design

Touit 2.8/12

When the angle of view becomes extreme, the retrofocus design of the Distagon lens can also be the ideal choice when the camera is not an SLR. Distagon lens types possess the low, image-sided, raypath angles that are particularly favourable for use with digital image sensors and also guarantee an extremely homogeneous distribution of brightness across the image field.

Distagon with 11 lens elements in 8 groups
Lens with aspheric surface
Lens made of special glass with anomalous partial dispersion
"Floating Elements" design

Smooth and reliable autofocus

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.

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.

Aspherical design

The aspherical lens design ensures consistent imaging performance throughout the entire focusing range as well as sharpness to the periphery of the image. The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations compared to a simple lens.

Floating Elements Design

Today’s camera technologies and high-resolution sensors demand continuous improvement of lens performance. Thanks to the use of the latest floating element design principles, optical aberration effects in ZEISS lenses are reduced to a minimum throughout their entire focusing range. This is achieved by variation of the axial distance between individual lens elements or groups. This adjustment of the lens-to-lens distance is coupled to the distance setting to ensure correct compensation at all times. The mechanical construction of these lenses is extremely complex and they must be assembled with utmost precision – both of which are key competencies of ZEISS.

Excellent resolution and high contrast

Richly saturated and vivid colours are a must in the creation of lasting impressions. However, stray light within an optical system leads to a lightening of the image that is particularly noticeable in the shadows. This reduces image contrast, with the result that exposures lack contrast and appear faded. To avoid this, ZEISS combines various specially developed technologies to reduce the undesirable effects of stray light.

ZEISS T* anti-reflective coating

All lens elements in SLR lenses from ZEISS feature the T*® anti-reflective coating and an optical design that produces brilliant pictures even in unfavorable lighting conditions. We vacuum deposit very thin, transparent coats on the surfaces of the lens elements to make them anti-reflective. Special substances, one by one, are vaporized with very high energy in a high vacuum, which are then deposited on the glass surface as a coating with precisely controlled thicknesses to achieve the desired reduction of reflections. The first coatings were applied by ZEISS back in the 1930s.
