Leica Summilux-M 24mm f/1.4 ASPH Reviews
Shutterbug compares the Leica Summilux-M 24mm f/1.4 ASPH to Leica’s Noctilux-M 50mm f/0.95 ASPH and writes;
“…The maximum distortion of the lens is 2.2 percent, which in practical terms is negligible. Even at f/2.8 only natural vignetting is present and that’s virtually, maybe completely, eliminated in digital capture on Leica M8-series digital rangefinder cameras.”
Web.me.com reviews the Leica Summilux-M 24mm f/1.4 ASPH and writes;
“Barrel distortion. While I did notice some on the 21, the 24 is absent of it in my time with the lens.. I did not see any distortion in any of my images with the 24 Summilux. Purple Fringing. Well, this lens does exhibit some purple fringing when shooting in certain types of lighting at 1.4 or F2. By F2.8 the lens is free of this effect.”
Kenrockwell reviews the Leica Summilux-M 24mm f/1.4 ASPH and writes;
“Bokeh, the quality of out-of-focus areas as opposed to the degree of defocus, is surprisingly wonderful in the center. Focus is always perfect. Rangefinder cameras have a huge advantage over SLRs with ultrawide lenses. Shoot this at f/1.4 in the dark at any distance, the the center of the image is always dead-on sharp at f/1.4. There no color fringes anywhere, on film or on the LEICA M9, when the subject is in focus.”

The very high-speed and compact Leica Summilux-M 24 mm f/1.4 ASPH. gives photo- journalists a new tool for their work. The lens is ideal for available light photography. Like the 21mm f/1.4, it consists of ten lenses in eight groups. Until the advent of state-of-the-art blank-press methods for aspherical lenses, it was not possible to create these new Summilux-M lenses. Hand assembled in Solms Germany, this meticulous craftsmanship also ensures long term reliability even in challenging conditions.
The correction of colour imperfections requires great deal of effort. and to that end this 24mm lens incorporates five separate lenses with anomalous partial dispersion. As a result, vignetting and distortion, the parameters traditionally difficult to control in fast wide-angle lenses, are corrected so well that they are hardly noticeable in practice. Even at an f-stop of 2.8, in effect, only natural vignetting is present. Patented rectangular lens hoods fit Series VII filters.
