Zeiss 25mm f/2.8 Biogon T* ZM Lens for Leica M, Black

Biogon T* 2.8/25 ZM The specialist for architecture and landscape... This lens features outstanding brilliance and resolution at all apertures and is a powerful addition to the 35 mm "standard wide-angle" lens. This 9-element lens is based on the symmetric Carl Zeiss Biogon design. Its stunningly high image quality and invisibly low distortion make this lens a creative tool for wide vistas, exciting landscapes, cityscapes and architecture. Why M-mount? • For more than 50 years now, passionate 35 mm photographers have been embracing the M-mount rangefinder camera system. From the lens designer's perspective, a rangefinder camera offers an exciting advantage over single lens reflex (SLR) cameras: more space. After all, there is no moving reflex mirror and drive mechanism. This allows for a short distance between the last lens element and the film meaning more opportunities for designing of superior lens types, including high performing wide-angle lenses. A passion ready for the challenge • For our lens designers, the chance to develop the Carl Zeiss family of T* ZM-mount lenses was a dream come true. They were free to follow their passion in pursuit of perfection in lens performance, taking full advantage of our uncompromising symmetric lens designs. The only limitation was to reserve 15 mm in front of the film for the TTL exposure metering, commonplace in M-mount cameras. The result is a complete range of the most advanced M-mount lenses ever made. Superior in every way • The Carl Zeiss range of T* ZM-mount 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. • Carl Zeiss T* ZM-mount lenses are specifically designed to minimize focus shift with aperture changes an important innovation withbig 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. For reliable performance, Carl Zeiss T* ZM-mount lenses are designed with a wear resistant filter mount and an extremely accurate rangefinder coupling mechanism.
