A versatile wide-angle prime for Leica M-mount rangefinder cameras, the Super-Elmar-M 21mm f/3.4 ASPH. is a unique lens characterized by its sophisticated optical design and impressively sleek form factor. Utilizing one double-sided aspherical element and four anomalous partial dispersion elements, spherical and chromatic aberrations and distortions are minimized and sharpness is maintained throughout the aperture range. The aspherical element also contributes to the compact form factor, and the manual focusing design permits working with subjects as close as 2.3' away.

Wide-angle prime utilizes one double-sided aspherical element to reduce spherical aberrations and distortion for improved sharpness throughout the aperture range.
Four anomalous partial dispersion glass elements help reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
Aspherical element also contributes a compact design measuring 2.1 x 1.7".
Manual focus design affords a minimum focusing distance of 2.3'.
The front of the lens has 46mm-diamter threads to accept optional filters and the lens is male threaded to accept the included lens hood.

    Super-Elmar-M 21mm f/3.4 ASPH. Lens is rated 4.9 out of 5 by 14.
    Rated 5 out of 5 by from Superb Super-Wide Angle Simply put, this might be the best super-wide lens in 35mm format. Very low distortion, flare free, and extremely sharp. In fact, this is perhaps the highest resolving Leica lens I have ever used. Very well made, smooth and well dampened focus. Screw on hood is much better than the older style clip-on hoods. It's expensive for a slower lens, but there is no need to stop down for sharpness; it's as good as it gets at F/3.4. Beautiful lens with a lot of character as well. I am very fortunate to own this masterpiece. I purchased it from B&H. No doubt it will become a legend in the Leica world. Thanks B&H......

    Rated 5 out of 5 by from Simply Stunning I cannot add anything to the comments of other reviewers except to say that this little lens is simply stunning in every way: Build quality, precision focusing, performance and especially in image quality. With a maximum aperture of f/3.4, it is a medium speed lens by Leica standards but with the high ISO capabilities and image quality of the M240, M-P and M Monochrom, the slow maximum aperture of f/3.4 is pretty much a non-issue. The 21/3.4 ASPH is small, light and produces outstanding image quality. You can't go wrong with this little masterpiece of a lens!

    Rated 5 out of 5 by from Beyond words I've used a lot of 35mm lenses to include Leica and Nikon. This is perhaps the sharpest lens I have ever seen or used. Not that being sharp is the most important factor, but trust me on this one. Amazing flare control, and the most controlled distortion I've seen in a 21mm lens in 35mm format. Its amazing how very little distortion this lens has for a super wide angle. Contrast is spectacular. Its brilliant at shooting into the sun for nice sunstar effects (18 pointed sunstar) which is what I want in a super wide. Build quality is superb and the new screw on hood is much better than the older style clip in hoods. Ergonomics are perfect i.e., size, aperture placement, tabbed focus ring. Simply one of Leica's best lenses in my opinion and one that will easily become a legend.

    Rated 5 out of 5 by from Amazingly sharp lens! I purchased this lens just days before heading to Cuba for a week-long trip. I wanted this wide-angle lens on my M (Typ240), to go along with a Nikon D5 and 70-200. It was a great combination. As an F/3.4 lens, it's way smaller than the F/1.4 21mm which makes it ideal as a companion on a trip. I found myself primarily zone-focusing the lens...looking at the aperate I was using and setting the focus and then just worried about composition. I had previously purchased the shoe-mounted 21mm finder, and if you're concerned at all about composition, it is something you will need when using this lens. The results were fantastic...terrific color rendition and razor sharp images, in a nice lightweight package. A perfect fit for a Leica M camera.

    Rated 5 out of 5 by from Update to earlier review I used this lens this past week at the North Rim of the Grand Canyon. For landscape and scenery work, this lens is superb and did not exhibit any of the wide angle distortion that I noted in my earlier review. In short, for this kind of photography, I couldn't say enough positive kudos for this lens. It's a terrific choice.

    Rated 5 out of 5 by from Sharp at all apertures This is an outstanding combination of small size and optical excellence. I routinely shoot it wide open without reservation, especially for interior shots. Great for street shooting, if you can get close to your subject.

    Rated 5 out of 5 by from An amazing lens, period! This is an amazingly crisp lens, with minimal distortion and still extremely compact. I would certainly not call it inexpensive, but I am still surprised that Leica did not price it for an extra as most folks would have still purchased it.

    Rated 5 out of 5 by from Careful what you mount this on!!! This 21mm on an M240/M10 is absolutely perfection.� You won't find a better performing lens on those bodies.� Mount this lens on a Leica SL and you will be disappointed.� It's a slightly older lens design and the SL does not have offset microlenses so the result is slightly soft images...a major disappointment.
