Leica Summilux-M 21mm f/1.4 ASPH Reviews
Opticsplanet reviews the Leica Summilux-M 21mm f/1.4 ASPH and writes;
“The pro-verbial Leica image quality is preserved even in the close-up range. Distortion is minimal and negligible in photographic practice. At f/5.6 this lens is free of artificial vignetting. With all these qualities, it is ideally suited for dramatic effects with monumental foregrounds and strongly receding backgrounds with distant horizons. Because an extremely large depth-of-field is already achieved with a slightly stopped-down aperture, sharp dramatic pictures can be made during live reportage photography.”

Leica 21mm 1.4 summilux aspherical, | Rating:
“At f1.4, central image is extremely well detailed even at the minimum focusing distance of 0.7 meters, thanks to the floating elements. The corners are very slightly softer at 1.4 but more than able to render sufficient detail, and of course there is noticeable vignetting wide open. Stopping down yields fantastically crisp, 3 dimensional quality with beautiful tonality, corners to corners. It has a “just right” degree of contrast, not too much to clip highlights or shadows. Form f4 down, this lens is probably the finest quality 21mm lens made for the 35mm camera. At 1.4-2, it’s the only 21mm of it’s kind. the ability to achieve selective separation of subject and foreground and background yields a totally unique image at 21mm.” – by P. Halperin

Leica Summilux-M 21mm f/1.4 ASPH Specifications
The Leica Summilux-M 21 mm f/1.4 ASPH. is the first and only 21mm small camera lens with this lens speed. The outstanding image quality, very large image angles, and compact dimensions make the Leica Summilux-M 21 mm f/1.4 ASPH a particularly versatile performer. At full aperture, the depth of field (DOF) is extremely shallow. As a result, in close-ups the main subject can be separated effectively from the background to create very expressive photographs. At a medium stop, the focal range is so great that entire scenes can be reproduced sharply. Because of the floating element, the very high resolution is retained even in the close-up range. Vignetting and distortion are both corrected excellently for a lens of this speed. A patented, rectangular lens hood fits Series VIII filters.
