This compact, moderate wide-angle lens is optimized to reduce stray light and reflections and is well suited for difficult lighting conditions. The combination of focal length and lens speed makes it suitable for a broad spectrum of applications. In the half-light of dawn or at dusk, or in interior spaces, the Distagon T* 2/28 lens is the perfect companion for the more daring photographer. It is at its best when the lights are low. Without forcing itself into the foreground, it discovers and highlights the details that would otherwise be lost in the dark.

When wide angle views go to extremes and beg the control via an SLR viewfinder, which means that the back focal distance has to be much larger than the focal length, a retrofous design called Distagon is the right choice.

Manually focusing a lens means controlling the image result from your fingertips. A good ergonomic design makes all the difference. ZEISS SLR lenses stand out with their large rotation angle which enables 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 precise engraving in meter and feet, and the depth of focus scale provide additional support for manually focusing.
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.
Today’s camera technologies and high-resolution sensors demand continuous improvement of lens performance. Thanks to the use of the latest floating element design principles, optical aberration effects in ZEISS lenses are reduced to a minimum throughout their entire focusing range. This is achieved by variation of the axial distance between individual lens elements or groups. This adjustment of the lens-to-lens distance is coupled to the distance setting to ensure correct compensation at all times. The mechanical construction of these lenses is extremely complex and they must be assembled with utmost precision – both of which are key competencies of ZEISS.
Dramatic perspectives and a view from extraordinary image angles – SLR lenses from ZEISS 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.
Noticeable quality and high value stability qualify ZEISS lenses for decades of intense 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.
