ZEISS Biogon T* 2,8/28 ZM

Take the road less travelled.

This classic, wide-angle focal length with a moderate perspective complements the standard 50 mm focal length and is an ideal tool for documenting your travels.

The ZEISS Biogon T* 2,8/28 ZM exhibits crisp detail without distortion at full apertures, even at the close-focus range. The optical construction minimizes flare, enabling photography against a strong backlight without compromising image quality. This lens has the widest angle of view that can be used with the integrated viewfinder on the Zeiss Ikon rangefinder camera, an additional 25/28 mm viewfinder is available. The Biogon T* 2,8/28 ZM is ideal for travel photography and is also well-suited for group and interior photographs when space is at a premium and wide-angle distortion needs to be minimized.

  • Features

    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).

    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.

    Robust design

    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.

    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.

    Lens Design

    ZEISS Biogon T* 2,8/28 ZM

    A lens with such a large field angle that it can capture as much of the photographer's surroundings as possible in a single shot – this is the origin of the name Biogon®. The largely symmetrical Biogon optical design enables the use of very compact, moderate to extremely wide-angle lenses, including with rangefinder and mirrorless system cameras. The lenses feature exceptionally good distortion correction, chromatic properties and image field flattening.
