The Zeiss Touit 12mm f/2.8 Lens (Sony E-Mount) is a wide-angle prime lens designed specifically for use on APS-C-sized image sensors, and as such provides a 35mm-equivalent focal length of 18mm. This lens is compatible with Sony E mirrorless cameras and supports all camera functions, including autofocus and exposure control.

The Distagon design of this lens integrates a floating element design that includes two aspherical elements and three partial-dispersion elements to reduce aberrations and distortion to produce high image clarity, sharpness, and even brightness. Carl Zeiss T* anti-reflective coatings have also been applied to all lens surfaces to improve light transmission and image contrast by minimizing surface reflections, lens flare, and ghosting.

The construction of the lens features a metal lens barrel with rubberized control rings for high precision when manually focusing. A rigid metal bayonet mount ensures accurate alignment and a nearly circular nine-blade aperture works to produce an aesthetic out-of-focus highlight quality.

 

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 achieve maximum compatibility on APS-C cameras of the Sony Alpha series with E-Mount (AF in video mode) we highly recommend using the latest Sony 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.

 

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 ZEISS as long ago as in the 1930s.
