After reading lots of reviews, I finally made the decision to purchase this lens. But what I got is defective! I had the same problem with Michael: the aperture blades buckled from f2 to f16. Actually the blades can't form a round aperture. The shape of the hole is irregular and is changing while turning the aperture ring. I just shipped it back today and will wait for my exchange lens. In one month, two lenses sold by B&H have the same defective problem. A couple of years ago, this lens had flare issue, then Leica fixed it. Right now it looks like Leica's QC need to be improved. I do not know what B&H or Leica will do with these defective lenses. Although B&H customer service told me that they never re-sell them, I still want to post the lens information in here. ... MoreAfter reading lots of reviews, I finally made the decision to purchase this lens.

I traditionally have been a Canon DSLR user. With my move over the last couple of years to more manual lenses (typically the more recent Zeiss offerings on the Canon mount) and a desire to find high quality small systems I can take traveling, my road led me to Leica. My only use of this lens has been on a Sony A7II camera body with a Voigtlander Close-Focus adaptor so my thoughts here will be on the lens itself and its marriage with the Sony body. Everything about the build of the lens lives up to the Leica reputation - exemplary in all respects save two comments. The aperture ring is a bit too loose and one can knock it to a different setting unexpectedly or without knowing.

Everything about the build of the lens lives up to the Leica reputation - exemplary in all respects save two comments. The aperture ring is a bit too loose and one can knock it to a different setting unexpectedly or without knowing. Secondly, and this may be matter of preference after using Zeiss for years, but I could have used a bit more throw to dial in focus with more precision. The mating of the lens with Voigtlander on the Sony is a great thing. One of the Achilles' Heel of all Leica systems has been their long minimum-focus distance. With the adaptor, you can half your minimum focus distance. While still not in macro-magnification territory, you can obtain some reasonably close (0.4m) shooting distances. The lens, adaptor and camera all fit together very snuggly, minimal movement and no light leakage. Performance of this lens is already well known, stellar, peerless as many have said. Usage on the Sony is generally exceptional with the lens really singing over the vast majority of the frame. It is a true feat to have a lens with such optical precision yet have a pleasing bokeh (see the flower picture). The lens is every bit as sharp wide-open as many lenses are at their best. Fringing is also well controlled as is the flare - if there was a problem with flare at launch, it has been addressed. However, the very extreme corners of the frame do experience marginal (splitting hairs here) softening. The Zeiss Otus 55mm had consistently sharper corners at the same apertures. It should be noted that this lens is not optimized for the Sony sensor, I have read that there are panes of glass on the Sony sensor that given the distance or proximity to the rear element of the lens, cause this softness for Leica-to-Sony adapted lenses. The shorter focal-length lenses having more difficulties up to and including discoloration issues. The 50mm Leica lenses seem to be just on the edge of having no impact. I would say for a lens such as the Noctilux, this would be a non-issue given its corner performance - but the APO is an unforgiving lens. Again, extreme corner performance we are talking about here. Overall, this tiny lens packs quite the performance - it's really quite impressive actually. I would caution others that using this lens on a Sony body as cheap substitute to a Leica body will not avail the full capability of the lens nor the Sony sensor given their respective designs. No free lunches... However, the handing and usage of the lens on the Sony make a great combination, particularly with the focus-peaking and magnification. Highly recommended lens!

I chose 50mm as my primary lens for my new M11 camera and could not be more pleased. The quality of build is apparent from the moment I unpacked and picked up the lens. Focus and aperture rings are easy to adjust quickly when taking photos. I won?t pretend to provide a detailed judgement of image quality, I?m just not that good of a photographer. So far all photos have been excellent with no vignetting assuming I did my job with focus and exposure. In conclusion, I am an old film guy and its good to be back to manual focus and less complication in my gear. I highly recommend this lens.

The Leica 50mm f2 is perhaps the best little all purpose lens ever designed! It is an all-around excellent tool for your camera. Since I shoot mostly outdoor secenes and landscape, I always carry one in my kit when I go on a hike or trip. Also, I carry a fast 70mm lens as well. These two cover 95% of all of my shooting in color or Black & White, film or digital (Leica M, Nikon Df, and Cannon.) JPG
Wow I purchased this lens as my ultimate stop and one and only one solution. I sold my 50mm summilux and 35mm summicron to finance this baby. It arrived brand new, sealed in gray box. What a shock! There is a resistance on aperture ring between f2 and f2.8 as well as at f16. When i looked at the blades, I could not believe my eyes. Just as the other reviewer mentioned, the aperture blades are not synchronized. Are you serious? I checked the quality control signature, I am in a shock! It is either something wrong with the design or the quality control. I had all lenses, from Olympus to Panasonic to Sony. M lens quality is second to none. And once you think you are at nirvana of lenses, it is such a disappointment. Leica needs to investigate this issue to figure out ... MoreWow I purchased this lens as my ultimate stop and one and only one solution.

Very disappointed frankly.
There is no better 50mm lens available for your Leica M camera. There are faster (Summilux and Noctilux), lighter (Summarit) and even higher performing (APO Summicron), but when taken as a total package (which of course includes price) then this lens really hits the sweet spot.The Summilux might be slightly sharper (might, and if so, very slightly), the APO is visibly sharper and the Summarit is lighter and cheaper, but there really is nothing that this lens doesn't do extremely well.At f/2 its fast enough for almost anything, and since it performs so close to its best even wide-open, there is never a need to stop down other than for increased depth of field.Some people complain about flare, but I've owned this lens for years, sold it, and just bought another ... MoreThere is no better 50mm lens available for your Leica M camera.

Yes, it will flare as all lenses will, but its no worse than the Summilux (the Summarit is actually the best at dealing with flare) and it is entirely controllable and predictable.Sharpness is impressive from corner to corner, as are contrast, color and bokeh. What can I say, I love this lens.
The Leica APO Summicron M 50/2 ASPH is expensive, but is simply one of the very best lenses I have ever used. It produces a bit more of the analytical look than my classics, but has more 'character' than my 'modern' 50s. Nice smooth color and value gradients. Yet, where it is in focus, it produces bitingly sharp images. First class micro-contrasts. Undetectably CA and distortions. Sharp from corner-to-corner. Built to last. Smooth operations. Does not block the M viewfinder. Nothing to complain.
There is a reason this lens has been a staple in the Leica lineup for 40 years: It is about as close to perfection as you can get. The only way Leica was able to improve on this design was the APO version which costs $8K - that says something about how good this lens is.It handles great - the aperture ring is way out front where it belongs, the focus ring is right in by the body where it belongs - you can run this lens by feel, just tweaking focus in the viewfinder. And it's a tiny thing - That is what the Leica M-System is all about. Small, fast, exquisite.All the sharpness you could want, great color, great contrast - a truly superb lens.This lens is a definite must in any Leica M kit.
This apochromatic lens, in combination with the 40 Megapixel color sensor of my Leica M10-R Digital Rangefinder Camera, produces maximum resolution of which any photographer could dream. This is the center of my photographic style. The apochromatic design focuses red, green, and blue wavelengths at the same plane and virtually eliminates chromatic aberrations. The weight of only 300 g (10.6 oz) makes it sufficiently compact to serve me as my primary every day lens, even though itis manual focus, without the convenience of auto-focus. For close-up photography a minimum focusing distance of 70 cm produces a Macro Reproduction Ratio of 1:11.3. Trying to find a true macro lens among the multitude of different Leica Mlenses is quite a challenge and I have resorted to ... MoreThis apochromatic lens, in combination with the 40 Megapixel color sensor of my Leica M10-R Digital Rangefinder Camera, produces maximum resolution of which any photographer could dream.

Trying to find a true macro lens among the multitude of different Leica Mlenses is quite a challenge and I have resorted to use my old analog (non-digital) Zuiko 50 mm f/2 macro lens with an adapter producing acceptable results. In summary, if your budget is not a concern, I would highly recommend the Leica APO-Summicron-M 50mm f/2 ASPH lens.
The original optical formula dates from 1979. There is a reason it is still in production, although mechanically changed in 1994: An amazing lens that is compact and sharp. Wide open slightly soft but nearly ideal as a portrait lens. Stopped down a bit it is hard to distinguish the quality from newer ASPH designs.
