I had my heart set on a Cron 2.0, but I read the reviews and they were spot on.
This is amazingly sharp, bokeh is beautiful, and the color is neutral. At 1.2 it vignettes in a beautiful manner, by 2.0, it's crystal sharp. Note at 1.2 it does purple fringe in high contrast areas when sun is out...not as bad as the older 1.1 version, but it's noticeable.

Using it on my Leica M10 Monochrom and it delivers brilliant results even And especially wide open. Build quality is first rate. Wish it came with a lens hood instead of that being a 110 dollar extra. Ended up purchasing a 52mm Sensei Pro for under 10 bucks and a 58mm snap on cover for under 5 bucks: Perfect solution. Need to use a filter? Add one between lens and hood. Use the hood to rotate a polarizer...
The focus ring is as smooth as they come. Throw is perfect.
Price performance is hard to beat, seriously!!

Ive been looking for a 50mm wide aperture lens for my Leica bodies.  I had settled on a used Summilux 50mm but when Voigtlander announced their new 50mm f1.2 ASPH I decided to research that lens.  Reviews were very good and the performance wide open was excellent.  At f1.2 its a half stop faster than the Summilux at half the price of a used one.  After using it for a month I find the lens outstanding.  I mostly use Leica glass but this lens stays on a Leica body always.  Very sharp, minimal vignetting wide open (use the f 1.2 Noctilux profile), no barrel distortion, and have not detected any color fringing so far. Beautiful Bokeh with a pleasing background.  I cant say enough good things about this fantastic lens.

Hands down one of the best 50mm lenses I have owned. After several weeks shooting it, I can say it is truly an amazing lens. Fit and finish is excellent and the rendering is fantastic. My only knock, it should come with a hood, but oh well, I will plunk down another $100 and complete the package.

Usually any lens faster than f/1.4 is considered a “super speed” lens.  Super speed lenses are known for being difficult to use, finicky, bulky, heavy, and not necessarily being all that sharp.  They also are known for being more susceptible to flare than their less exotic f/1.4 and f/2 cousins, not to mention extremely expensive.

This Voigtlander is a super speed lens that suffers from none of those usual downsides.  It is fairly compact, not excessively heavy, but most unexpectedly it is very well-behaved in almost all situations.

The lens is very resistant to flare.  It has very low distortion, is very sharp, does not suffer from focus shift and generally is just as easy to use as a less exotic lens.

For those expecting a budget Noctilux, this isn’t it.  Actually it has a look very much like the Leica Summilux ASPH, which is a very good thing, and then it can open up an additional half stop.  It isn’t quite as well corrected as the Summilux (that lens is apochromatic and this one isn’t), but it is very, very close, not to mention it has the exact same weight.

I’ve had this for about two weeks now and so far am very impressed.

This lens is a rare steal. Stunning image quality, sharp wide open, creamy bokeh, and solid but compact build on my M10. It’s everything a Leica or rangefinder lens should be, at a fraction of the cost. And it’s a true joy to shoot with. It’s the lens I most frequently have mounted. Highly recommended!

Great lens, softer wide open, but sharp and nice edge to edge sharpness when you stop down. It's a but heavier that the Summilux, but a very good plan b option.

This is a great sharp lens, I use it on the Leica M10-P and M10-Monochrom cameras. The price is right on target and rivals the more expensive lenses.

Smooth color and shade gradients. Beautiful bokeh. Sharp, but not harsh. Well built. Nice portrait lens.

Great lens at a fair price. Outstanding Japanese optics for a fraction of what a Leica will cost you. This 50mm is a smart choice for Leica rangefinder cameras. It's sharp and it pairs well with the M10's 24-megapixel sensor. My rangefinder calibration was spot-on with this Voigtlander.
