The Distagon T* 2,8/15 ZM is a fast lens for its focal length, allowing for hand-held photography under difficult lighting conditions. The lens is made in Germany and incorporates a very complex optical design using exotic optical materials such as barium dense flint with a high refractive index and fluor crown with anomalous partial dispersion. It uses aspheric lens elements and an internal focus mechanism for distortion-free images and consistent performance over the whole frame and across the entire focusing range. The standard center filter compensates for the natural vignetting effect and provides even tonal reproduction across the image field.

The lens is made in Germany and incorporates a very complex optical design. In our manufacturing facilities in Germany we have unrivalled experience in designing and manufacturing the most advanced lenses in the photographic world. Examples include exceptionally high performance lenses for semiconductor manufacturing, cinematography and top quality medium format cameras.
The ZEISS range of 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.
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.
The mount and control elements of all ZM lenses are made of metal and are designed for decades of intensive use. The high-quality craftsmanship of the all-metal mounts, the easy-to-grip metal focus and aperture ring and the robust front bayonet and filter threads ensure an amazing photographic experience.
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.
