Leica 21mm f/1.4 Summilux-M ASPH [11647]

The Leica 21mm f/1.4 Summilux-M Aspherical Lens is a super-wide angle lens designed for high-speed performance. Its bright f/1.4 aperture allows for an extremely shallow depth of field (DOF), and at a medium f/stop, the focal range is so great that entire scenes can be reproduced sharply. Because of its floating element design, the very high resolution is retained even in the close-up range.
