The Zeiss 21mm f/4.5 C Biogon T* ZM 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.
This lens is NOT recommended for use with Leica M9 rangefinder digital cameras. The angles of this lens are too steep for the sensor design and it results in a red color shift at the edge of the frame.
1/3 stop interval click stops allows for exact exposure
