A high speed lens gives you a huge amount of freedom in taking your photographs, as you can either make the most of available light, not having to worry about disturbing a moment with a flash, or create spectacular effects with a shallow depth of field or harmonious bokeh.
Ideal for every use, for both photography and professional video shooting. With the de-click feature for the aperture function, you will handle unexpected changes in brightness and difficult lighting conditions seamlessly – simply with a switch directly on the lens. Every pan shot will be successful. In addition, you can use the aperture ring of the lens to preset the aperture just as you would do with special video lenses. Here as well, you will love the diverse and especially precise focusing options of the lens – manual as well as automatic.
Design of the autofocus system requires extremely accurate shifting of particular lens groups. While this is normally achieved via mechanical coupling from the camera body, ZA lenses feature a built-in SSM (Super Sonic wave Motor) focusing system for even more refined AF performance.
Its metal barrel and bayonet as well as elaborate protection against dust and spray make the lens perfect for shooting in demanding outdoor conditions – and also guarantee its constant readiness for many years of intensive use.
Compact yet extremely capable – ZEISS worked in close collaboration with Sony to create a high-precision lens, containing aspherical lenses as well as extra-low dispersion glass to ensure a portable size, while delivering exquisite image quality at the same time.
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.
