[Canon RF] Using this adapted to a Fuji XT3 and it has quickly become my favorite lens to use. Unlike the Fuji lenses, the manual focus is a joy to use. Very smooth operation with the MF ring. Image quality is great. F1.2 is fun to use and gets very sharp by F5.6. Wish they had a Nokton 23mm to match the quality of this one. Tried this lens on my A7RIII also. Works well, but there is just something about the rendering with the Fuji that is special.

[f/1.2] Using VM mount on Sony A7rII via Voight adapter and Leica M6.  Works great on both.  Compact, solid, elegant.  Beautiful images wide open and stopped down.  CV on a roll lately.


FWIW, the VM is somewhat smaller, which I like.  


Theres a very extensive discussion of this lens over at Fried Miranda.  Steve Huff goes on at length comparing the E-Mount vs VM - reaching no real conclusions.

[f/1.2] It's a lovely lens that produces a rich, cool-toned contrast similar to the Zeiss Milvus line, but with a dreamlike character when shooting wide open. Stop down to f/2, and it's as sharp as most will need. Conveniently sized and just the right weight, with a smooth focus ring and a clicking aperture ring. 40mm is a really nice focal length for a small, fast lens like this. If you're someone who likes to shoot manual focus, this scratches the itch. :)

I personally love lenses that render with more character since a lot of high-resolution full frame sensors can be a bit too detailed/sharp for my taste, when combined with razor sharp optics — so having something to take the edge off and produce a bit of an organic look is really nice. That being said, the aberrations are still controlled to an extent; they're only ever a bit overwhelming when shooting at f/1.2 at minimum distance — but of course, you would generally stop down when shooting that close anyway, so I think Voigtlander has balanced the rendering quite nicely.

And of course, Canon makes it stupid easy to manual focus on their R-series cameras — so if you have both Canon and Sony, I highly recommend this lens for the RF mount. Very much looking forward to future RF lenses from Voigtlander!

[Canon RF] I purchased the Nokton 40mm F/1.2 for my Canon EOS R7. This lens is tact sharp and well built. Keep in mind that this is a manual focus lens, but don't let it steer you away. This lens communicates with your camera and eye detection works flawlessly. The focus ring turns smoothly and I love the aperture step clicks. I'm very happy with my purchase and look forward to using more of Voigtlander RF manual lenses! :)

[1.255 lb] I have had the Voigtlander Nokton 40mm f/1.2 lens on my Leica M10 for about a week or so and it is great. I agree with all the other positive reviews. I use it mostly for street and landscape/seascape photography and it is the perfect focal length for those. There is one very minor thing that I don't care for, and that is the distance scale on the focusing ring, feet are in red which are hard to read on the black lens.. That should not be a deal breaker or discourage anyone from getting this lens.

[Manual Focus] I have had this lens for over a year now. It is usually on an M240. The combination of the great color of the 40mm and the M240 CMOS sensor makes for great natural color. The field of view seems to always work, too. All in all this lens has yet to disappoint me in the time I have had it.

[55°] Great performance, especially for the money. Originally purchased for my CL but it now is my main M6 optic. It just plain works. I'm getting smooth bokeh but edgy sharpness. It also gets along well on my Fuji X bodies which can be hit or miss for me with many adapted lenses. Beautiful build quality that is tactilely gratifying, too.

[1.255 lb] Awesome lens for the money. Very cinematic look and feel. Off beat focal length.

[Manual Focus] I bought the lens on the morning of my recent one-week stay in NYC and I don't regret it.
I put on the lens on my M240 in the adjoining waiting room close to the entrance of B&H (like many others).
I used it for most of the pictures I took during my stay (apart from a few wide-angle pictures with my Super-Elmar 21mm and a few telephoto pictures with my Summarit 90mm).
I really loved the quality of the pictures and being able to rely on an opening of 1.2 is very convenient in some streets in NYC (often with low light on one side of the street).

[58 mm (Front)] I bought this to use on my Canon R mount bodies. I also own and use the Canon RF 50mm f1.2 lens, which is truly exceptional. The downside is that the Canon 50mm is big, heavy, and very expensive. I don’t really need AF for portrait and similar work. So I am pleasantly surprised at the modest size of the Voigtlander 40mm. Also, it is exquisitely made and a joy to use.
