If the copy lens will be sold für $500-$600, it will have a good chance of success in sales. If it sells for $700-$800, it will most likely not be able to compete with the CV lens. My prediction.

Agreed. Although even if a little more expensive, the looks play in favor of this lens; soooo much nicer than the pseudo-vintage CV. That looks like it's inspired by the worst of German design of the 50s and 60s, the Bessamatic and its lenses or some such, while the Leica M stuff represents some of the best of German design of all times. That, and the focus stick...

Hi Raid, please look at the up left corner there is an information bar on the top. 仿八枚 means 8-element replica. M35F2A is the Asph version. So the first photo in the comparison is replica.

Similar cost. Great lenses.

Which lens is a better buy? Why?
No interest in the Voigtlander. I already have a bunch of boring lenses.

I have very few CV lenses compared to what I have in Leica lenses.

No interest in the Voigtlander either and apart from the above, if I'm going to get an extra lens at all I would need an LTM lens. Preferably a bare brass or black paint one!

How can a lens be boring? Is it not the photographer who has to let the lens live?

I assume he was talking about the rendering, bokeh, so-called the characteristic of the lens. Like I think Leica Asph lenses are kind of boring to me even though they are quite sharp. But I do like the 50mm f0.95 Asph, its performance in low light is fantastic.

This is a good catch. I remember the issue with 7Artisans being discussed online then.

Once built and flare issues fixed (by painting internals) I will buy one in black. Exact same thing I did for the 7artisans 28 1.4, buy the first batch of ones with internal reflections fixed.

I've been offline and out of the loop for a bit but I am just seeing this and getting caught up on the thread! How exciting this is, the V1 Summicron was a lens I have long wanted to try but I had no interest in paying the going rate, but this looks like a wonderful option (regardless of it being a "copy"). I can totally appreciate the effort going into this creation and also appreciate the craftsmanship involved.

I don't know if I can commit to buying (without knowing the hard pricing details yet other than the approximate) but I would definitely be an interested party for a black one.

Thank you so much for sharing this with the community and I look forward to the continued development here!

Very interesting endeavor there, Kevin. I wish the manufacturer luck in the completion of his project. I can see this turning into a boutique market, with the manufacturer offering a la cart service for whatever plating/paint/brass you want. If it goes well, put me down for a classic chrome version.

Update:

UPDATE: All the prototype lenses have been shipping around among the test people to seek feedback. Now the maker could finally take a prototype back in the lab, get it tuned, and prepare to send it to me. The package might take a week or so to get to the state. I can't wait to play with this lens.

*Please let me know if you want me to test the lens in specific ways. I will try my best to fulfill your request.

First of all thanks Kevin for sharing this thread.
I am keen as well on the replica lens.
Aside, I do wish in the future they will produce 50mm noctilux replica and 35mm 1.4 pre-asph steel rim version. Cheers!

The classic - if you mean original - version is not chrome, but aluminium. Only the small ring with the red dot on it is in chrome.

You are very welcome. I am having fun while doing this. Now I even get a chance to play with this lens.

I also wish he could bring some more interesting project to us. 50 Noctilux would be awesome.

You know what would really cool? An M-mount version of the Canon 28mm f/2.8 LTM. It's such a sweet handling lens, and an iconic 28mm.

Yea you are right. The reproduction was black paint S-Mount in 2005. I have this one in my collection. I also have the original Nikkor 35 1.8 LTM version. But this one haven’t been reproduced before. I guess it’s the one he mentioned.

Is there any difference between the two, optically?

Kevin has got what I meant. The LTM version is rare-ish, expensive and often in poor condition. If old lenses are to be reproduced then the Nikkor would be an excellent candidate.

There isn’t any optical difference between the original and reissue. The only difference I can tell is the modern greenish coating has been used on the new lens.

Jonny shared the comparison photos between the original and reissue. Very interesting post.

I agree! But there are already too many classic lenses waiting for the maker to produce now.
