Leica 21mm f2.8 ASPH (E55) Lens
Pricing: $4,295.00Leica 21mm f2.8 ASPH (E55) Lens Overview
Extreme possibilites
This compact ultra-wide-angle lens delivers outstanding detail and superb contrast even at full aperture. And the highest level of image quality is maintained even in the close-up range. Distortion is minimal, and negligible in photographic practice. With its ultra-wide imaging angle of 92°, it is ideally suited to landscape photography featuring dramatic effects. The foreground appears monumental, while the rapidly diminishing background creates a wide horizon. This focal length is also ideal for photojournalists who have to shoot right in the midst of the action. Since it delivers extremely sharp images and good depth of field at the widest aperture settings, very good picture results can be achieved in gruelling photojournalism assignments even without precise focusing. Combine this remarkable lens with the ultra-short shutter delay and aperture priority automation of the LEICA M7, and the result is the fastest camera system in existence.
