ZEISS Biogon T* 2,8/21 ZM

Widen your view of the world

The spectrum of ZEISS ZM lenses for digital and analogue rangefinder cameras combines advanced lens design and superior-quality materials and workmanship to deliver impressive results. The 12 different lenses cover focal lengths from 15mm to 85mm and a range of specialist and more general uses. All at prices that compare favourably with other rangefinder lenses of this superb quality.

The Biogon T* 2,8/21 ZM offers outstanding performance and extreme resolving power even when shot wide open, with virtually no distortion, excellent control of flare and ghosting and superb contrast rendition across the entire frame. The slim lens design is easy to grip and focus, and uses a standard 46 mm filter diameter similar to many of the other ZM lenses and allows filters to be interchanged between the lenses. The lens is rangefinder coupled for easy focusing and the optional 21 mm viewfinder is available for accurate image composition. The Biogon T* 2,8/21 ZM is suitable for many different wide-angle applications including reportage work, landscape and architectural photos.

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.

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.

Excellent resolution and high contrast

Richly saturated and vivid colours are a must in the creation of lasting impressions. However, stray light within an optical system leads to a lightening of the image that is particularly noticeable in the shadows. This reduces image contrast, with the result that exposures lack contrast and appear faded. To avoid this, ZEISS combines various specially developed technologies to reduce the undesirable effects of stray light.

Virtually distortion-free optics

Dramatic perspectives and a view from extraordinary image angles - ZEISS lenses open up new composition possibilities. Distortion would disrupt the composition because straight lines, whose image does not go through the image center, would be reproduced with a curved shape. This annoying effect is accordingly and largely compensated through elaborate optical designs at all focal lengths.

Minimized Focus Shift

ZEISS T*® ZM-mount lenses are specifically designed to minimize focus shift with aperture changes – an important innovation with big benefits for rangefinder photography. As a result, you can expect improved accuracy of the rangefinder-defined focus. While the precise 10-blade aperture with 1/3 stop interval click stops ensures exact exposure.
