Illuminate your ideas.

The exceptionally bright medium telephoto Sonnar T* 1,8/135 ZA lens by Carl Zeiss captures detailed portraits and close-ups, with superb resolution and a shallow depth of field, enabling you to visually isolate a scene through the use of beautiful background blur. Fast autofocus and a 135 mm focal length make it ideal for capturing fast-moving sports and wildlife. The elaborate mechanical design of the interior focusing of the optics also enables outstanding image quality for exposures on very close objects. Its aperture of 1.8 gives you the flexibility to get up close to your subject, even in difficult lighting situations.

High-Speed Lens

Impressive photographs captured in low light always begin with a fast lens for a system or SLR camera. Because, a fast, high-performance lens captures as much light as possible. And a lens with a large maximum aperture leads to the best results when shooting in unfavourable light.

Full frame compatible

ZEISS lenses are suitable for digital Sony Alpha cameras and have been optimized for film and sensors up to full 35 mm format (24 x 36 mm).

Ideal aperture with nine blades

Photographers want to guide the observer through the image. Minimal depth of focus is often used as a design element. This keeps the background intentionally blurred to keep the attention of the observer on the main subject. These different representations of the blurred areas, as well as the quality of the transition, are referred to as the Bokeh of a lens. The finely tuned features of the optical design on ZEISS SLR lenses ensure a particularly harmonious effect of the blurred areas of the image. The nine diaphragm blades and the resulting, virtually circular aperture on ZEISS SLR lenses are crucial to favorable rendition of highlights in the fore and background.

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.
