The Zeiss Touit 1.8/32 E-Mount 32mm f/1.8 Lens For Sony NEX  is a normal length prime lens designed specifically for use on APS-C-sized image sensors, and as such provides a 35mm-equivalent focal length of 48mm.
This lens is compatible with Sony E mirrorless cameras and supports all camera functions, including autofocus and exposure control.
The Planar design of this lens is a highly successful optical construction that inherently corrects for most aberrations and distortion while offering high overall sharpness and image clarity. Additionally, Zeiss T* anti-reflective coatings have been applied to all lens surfaces to reduce reflections, lens flare, and ghosting to produce imagery with high contrast and color fidelity.
The physical construction of the lens features a metal lens barrel with rubberized control rings for high precision when working with manual focus. When working in autofocus modes, the focusing system of the lens offers smooth and reliable performance with high precision and control. A rigid metal bayonet mount ensures accurate alignment and a nearly circular nine-blade aperture works to produce an aesthetic out-of-focus highlight
Sony E Compatibility
Designed for use on Sony E-mount APS-C mirrorless cameras and provides a 35mm-equivalent focal length of 48mm. The lens offers complete compatibility with all camera functions, including accurate autofocus and exposure control. It features a wide f/1.8 maximum aperture that aids in low-light shooting as well as greater control over the focus plane for shallow depth of field and selective focus applications.
This lens features a Planar optical design that works to eliminate a variety of aberrations and distortions in order to produce an image with high clarity and sharpness. A Zeiss T* anti-reflective coating has been applied to each lens surface to help minimize surface reflections in order to improve light transmission and provide greater image contrast and color fidelity.
The lens features a rigid, durable, yet lightweight, metal barrel with rubberized control rings to offer improved handling abilities. A metal bayonet mount aids in consistency and an ensured connection between the camera and lens. Additionally, a nine-blade, nearly circular aperture is used to smoothly render out-of-focus highlights.
Magician of the moment
A compact standard lens with autofocus, especially designed and constructed for compact system cameras like the Sony Nex, Sony Alpha and Fujifilm X Series cameras. A lens that makes it so easy to spontaneously capture your special moments and preserve them in perfect pictures.
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.
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.
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.
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.
