I can not agree with the remarks of the previous speaker. I use the lens with a Novoflex adapter to a NEX 5N and regularly get really great results. The Bokeh at f1.4, although in fact not particularly pretty, but it improves considerably when you stop down to f2. For the game with the depth of field as there is still a lot of room. The mechanical qualities of the lens are almost beyond reproach. I have never used such a super processed optics. That you focus manually and the aperture must be set manually, I find not bad, but on the contrary just delightful. You can also a lot to do so if one is constantly forced to adjust virtually everything themselves. Also worth mentioning, I find the awesome small dimensions, moreover. Although the part would even work on full frame or a Leica Bessa, it is significantly smaller than eg. The Sigma 30mm 1.4. That is another reason why the owners of mirrorless system cameras should take a look at the lens series of Voigtländer. The thing fits just great on this new small super snapping (and look bad does not do it well). Voigtländer offers objective way, in two versions. In the so-called. SC version, the lenses are simply coated (sc = single-coated). This contrast is not as good as in modern multi-coated lenses. What now first times sounds only drawback for some people makes a lot of sense. One only has to consider time, how much effort many give shutterbugs nowadays to get added with elaborate post a look, as it has produced 40 years ago cameras. The SC version that is no problem. She is also very good for black / white photography. If you value high contrasts, on the other hand should better the MC (= multi-coated) Get Variant. Both are usually about the same price. I opted for the SC version and am very very pleased with the look of the images. Very muted colors and an image characteristic that I will simply call "classic". The focus is also impressive. At f1.4, the edges are not really great and the contrast could be better. But in the center it's pretty good. Dims the Nokton at f2 well and from about f3.5 really sharp. Besides my Canon 50mm 1.8 II, which is almost the same, can match any of my other lenses, not the Tamron 17-50 2.8 non VC not the Canon 15-85 IS and certainly not the aforementioned Sigma 30 1.4, which I now that I have the NEX and this Voigtlander Nokton, barely used. Yes, and why only 4 stars? Because I now times very high demands on the top-rated and have Nokton not free of weaknesses. The mentioned Bokeh at open aperture is a Wermuth drop for me. I would not deny it. And a great pity is that the minimum focus distance is approx 70cm. This is in close throng so many evening event, for the good piece is indeed made to be a bit too much for my taste. It would certainly be great if you could at least sometimes ran a hand's breadth closer to the subject. That a good adapter simultaneously with more than 100 euro record suggests course is also pretty stupid, but I want the Nokton accuse them now. Finally, it is not nunmal NEX Lens, but a Leica / Bessa.
CONCLUSION: As long as the Sony SEL 50 1.8 not yet available (and maybe after that), the Voigtlander Nokton 40 1.4 for NEX-users definitely a recommendation is worth. For Micro Four Thirds cameras I might not recommend the lens because it has a very good competitor with the M.Zuiko 45 f1.8, which is also still cheaper. The game manual with a look of this quality makes mechanical but definitely fun and wanting more. The Color-Heliar 75 f2.5 I have in any case already bookmarked me.
