ZEISS Ikon Biogon T* ZM 2.8/28 Wide-Angle Camera Lens for Leica M-Mount Rangefinder Cameras, Silver

Take the road less travelled The 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 25/28mm 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.

• 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.
• EXCELLENT IMAGE QUALITY: ZEISS lenses offer 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, and virtually zero geometric distortion, ensuring precise accuracy when reproducing shapes – especially useful when photographing products and architecture.
• 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.
• 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.
• 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.
