Magician of the moment

The best of two worlds. Just like a 50 mm lens in 35 mm photography, the Touit 1.8/32 offers the same angle of view as the human eye. However, optimised for use with APS-C format sensors, it is simultaneously a lens that is so light and compact that it can be taken along simply anywhere and everywhere you go. Whether you are shooting portraits, landscapes or spontaneous snapshots, you will never cease to be amazed by what a Touit 1.8/32 can tease out of your camera. It is quite simply the ideal companion for capturing perspectives and colour- and lighting moods in perfect pictures.

Note! Zeiss has released a new firmware update for the Touit lenses with e-mount version.

The changes are for Touit 2.8/12 E-mount & Touit 1.8/32 E-mount:
With this version, the lenses also support phase detection autofocus and the fast hybrid autofocus of newer Sony E-mount cameras.

As of  Feb. 2015 all Touit e-mount lenses are already supplied with the new firmware.

ZEISS Touit 1.8/32 Standard Lens with Sony E Mount

Design
The Planar lens type is the most successful – and the most frequently copied – lens design of all time. It offers lens calculators numerous opportunities for almost complete correction of all optical aberrations, and is therefore even today the basis for the design and construction of modern, high-performance lenses. Modification of this proven, six-lens, basic design can achieve significantly improved performance for use with today’s image sensors.

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 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.

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.
