Be inspired by this compact wide-angle lens with a moderate focal length - the perfect addition to your light, mobile camera equipment.

The ZEISS C Biogon T* 2,8/35 ZM will inspire you with uncompromising image perfection, even at full aperture. The “C” in the title indicates another outstanding feature: Unusual for a lens in this class, its speed of 1 : 2,8 allows for an exceptionally compact construction. With a focal length of 35 mm, it is incredibly versatile and its high performance and compactness make the ZEISS C Biogon T* 2,8/35 ZM an ideal addition to your equipment. Whether you are traveling through impressive landscapes or visiting cities, compiling a news report or attending an event, this little all-rounder always proves a comfortable and reliable companion.

Excellent image quality

The range of ZEISS T*® lenses offers the highest possible standards in terms of performance, reliability and, of course, image quality. Quite simply, they are superior in every way. You can count on highly advanced flare control for crisp and brilliant images, for example. And virtually zero geometric distortion, ensuring precise accuracy when reproducing shapes – especially useful when photographing products and architecture.

Smooth, precise focusing

Manually focusing a lens means controlling the image result from your fingertips. A good ergonomic design makes all the difference. The user-friendly focusing ring on ZEISS lenses with an ergonomic finger rest is perfect for fast, precise focusing. Changes are immediately visible in the viewfinder. The high-quality focusing mechanism moves smoothly without play, thus also supporting the intuitive interaction with the focal plane.

Ideal aperture properties

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. The ZM lenses feature ten aperture blades. The almost circular aperture helps to create a particularly harmonious effect in the out-of-focus areas of the picture (bokeh).

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.
