Zeiss C-Biogon T* 21mm f/4.5 ZM Manual Focus Lens Super Wide Angle - Black
The Legendary Super Wide-angle Traveler: This compact super wide-angle lens produces distortion-free images at all apertures. The C in the C Biogon T* 4,5/21 ZM name stands for both ‘compact’ and ‘classic’, the latter referring to a legendary Zeiss design from 1952. Smaller and lighter than the Biogon T* 2,8/21 ZM, it is ideal for traveling and for photographing unobtrusively in public places. The lens is rangefinder-coupled for easy focusing and the optional 21 mm viewfinder is available for accurate image composition. Combined with a digital rangefinder camera with a 1.3 crop factor, the lens has an effective focal length of 27 mm. The C Biogon T* 4,5/21 ZM is an ideal lens for many different wide-angle applications including travel, architecture, landscape and interior photography.
The Zeiss 21mm f/4.5 C Biogon T* ZM Manual Focus Lens is a super wide angle lens designed for full integration with TTL-exposure metering. It has a minimum focusing distance of 1.8' (0.5 m), and offers ultra-sharp resolving power and next to zero distortion. Like its classic predecessor from 1952, the optical performance is stellar and destined to make the same history. Remarkably compact and lightweight, it is the ideal super wide angle lens for travel and outdoor photography.
The Carl Zeiss range of T* ZM-mount lenses offers high standards in terms of performance, reliability and, of course, image quality. 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.
