ZEISS Ikon C Biogon T* ZM 2.8/35 Wide-Angle Camera Lens for Leica M-Mount Rangefinder Cameras, Black

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. IDEAL APERTURE PROPERTIES: The finely tuned features of the optical design on ZEISS ZM lenses ensure a spectacualr bokeh, with particularly harmonious effect of the blurred areas of the image. The ten diaphragm blades and the resulting, virtually circular aperture on ZEISS SLR lenses are crucial to favorable rendition of highlights in the foreground and background. 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. 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. 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.
