Rangefinder shooters who love to shoot in dim light and adore wider angles are going to be quite happy with the performance that the Leica Summicron-M 28mm f/2 ASPH. delivers. It's expensive, but it's sharper and faster than Leica's own Elmarit-M 28mm ASPH. at wider apertures.

Sharp from edge to edge at f/2; Nominal distortion; Wide aperture; Fairly compact; Includes lens hood

Expensive; Close focus limited to 0.7-meter; Lens hood is huge; Manual focus only

IThe most compact lens in the entire portfolio of M-Lenses, making it ideal for street, reportage and travel photographers

Journalism; and any place where you absolutely need f/2 instead of f/2.8

This 28mm f/2 is big enough to block the camera's viewfinder; The Leica 28mm f/2.8 is a smaller, lighter lens that won't block your viewfinder, and has the same fantastic optical performance for a fraction of the price

Originally wanted the 28mm Elmarit, but My Leica dealer didn't have it, but did have the Summicron. Bought it 10yrs ago for around $3000. At the time it was the fastest 28mm Leica made. That was very important to me because at the time I loved shooting wide. This lens is very sharp.

The 28mm/2 ASPH is far and away the best lens in the 24-28mm range that I have used. It is extremely sharp and relatively smooth in out of focus areas, producing excellent results in photojournalistic crowd shots of people at f/5.6 and f/8.

Sharpness, low light and isolating capabilities, convenient focusing tab; Excellent construction

Sometimes large flare patches occur if a bright object is just outside the frame; Hood is bulky and cuts into viewfinder frame

The image quality of this lens is second to none! Whether you use this lens wide open or stopped down, you will not be sorry. Wide open it's a little hard to focus on the M9 because the image in the rangefinder of the M9 is very bright.

Our first M mount lens test concerned a Summicron- M 50 mm f/2.0 model so a full frame standard and classic device. By and large every full frame camera owner which treats his or her hobby seriously should have that type of lens in their arsenal.

excellent build and barrel quality; very good image quality in the frame centre; good image quality at the frame edge; low chromatic aberration; distortion corrected in a splendid way

huge vignetting; very steep price tag

The Leica Summicron-M 28mm f/2 ASPH. ($4,295) is an excellent wide-angle lens for M-mount cameras. It captures images that are sharp from edge to edge at every aperture, but carries a hefty price tag. It's the best rangefinder lens that covers a wide-angle field of view, outclassing the Zeiss Biogon T* 2,8/25 ZM($1,261.00 at Amazon), Zeiss Biogon T* 2,8/28 ZM($1,261.00 at Amazon) and Leica's own Elmarit-M 28mm f/2.8 ASPH. in sharpness, and capturing twice as much light as those lenses at its maximum f/2 aperture. Even when you consider its price, it earns our Editors' Choice award on its merits. Like most rangefinder lenses, the Summicron 28mm is quite compact at 1.6 by 2.1 inches (HD) without a hood. It's larger than the Elmarit-M 28mm (1.2 by 2 inches, 6.3 ounces), and a bit heavier at 9.6 ounces. Its front element supports 46mm filters, the same size supported by other wide-aperture Leica lenses like the Summilux-M 50mm f/1.4 ASPH.($4,395.00 at Amazon) and the Summilux-M 35mm ...

The Leica Summicron-M 28mm f/2 ASPH. is a sharp, fast, wide-angle optic for Leica rangefinder cameras; it's expensive, but an excellent performer.
