I wonder why this thread did not get any photos - apparently a lot of folks love this lens.

Sorry, I meant to say as many as for example our beloved 40mm 1.2

I tried using VN 35/1.7 and ZM 35/1.4, and CV 35/2 APO for Sony.
Each presents top quality image in sharpness and color uniqueness.
VM 35/1.7 is now low price and indeed one of the finest 35mm lens.

Nice shots! It was one of my favorite lenses and I only sold it when purchasing the Leica 35/1.4 FLE. In some ways the Voigtlander performed even better though.

Thank you Fred.
I love it so much. Thing is, after 35/1.5 was released last year, I wanted to swap my 35/1.7 for it. I haven't done it yet as I cannot really tell if its worth extra money. I like new lens size and I love that brass version paint, but not sure if swapping and spending more money will give me any advantage. Just to put it in perspective - I don't know how much would I get for my 35/1.7 - maybe £550. Then I would need to add another £300 for brass 35/1.5.
What do you think?

I'm not sure, if the new CV35/1.5 is optically better at all? There were some information about midzone dip on fast apertures. I've put focus tab on Ultron and using it is much much better now.
Really love this little gem!

Yes, it's this one. It fits and works nicely. It's definitely not the prettiest solution, but it's very functional.
IMHO using the lens with this tab is much better than before.

Just a warning to anyone buying one of these used, avoid the LTM version. There are two versions of the M mount, one that looks like the old LTM version and has the aspherical inscription in red on the front and a 0.9m mfd. Avoid this old version in both the l39 (LTM) and M version, they are prone to haze and develop a wobble issue thats hard to fix. Also the haze develops in between a set of lens elements thats cemented together.
I bought one off a Japanese auction site and there was no mention of the haze and i did not check it until recently so i cant even return it. The photos still look great when there is no backlighting, there is a lot of hazeflare when shooting it into light. Its like having a permanent diffusion filter on it now...oh well, will just have to make the most of it
I usually do my research before buying a lens but i was thrown off by popular reviewers stating that the m mount version is the new one but it turns out there is an old and new m mount version of this lens.
If you are buying the M mount version make sure its the new M mount version.

My understanding was that prior to the VM version released in 2015, the previous 35/1.7 LTM was only released in LTM. CameraQuest has a ton of info about current and past Voigtlander LTM and M lenses: https://cameraquest.com/voigtlen.htm and there is nothing to suggest there was an 'Aspherical' M version prior to the 2015 version.

Yes, there's no entry regarding an M-mount version of old 35/1.7 (1999) in Cosina archives where they list all discontinued lenses and I've never heard of an M-version either. I had the LTM lens at one point. Maybe somebody could have stuck an adapter ring to it and sold it as M-mount lens at though.

The Vintage Line Ultron 35/1.7 VM that came out in 2015 is totally different in terms of optical design etc.

This is the more plausible explanation.
The original LTM came in at least two cosmetic variants, with differences in the knurling on the focus ring. There was a claim that the so-called later version wasn't prone to the problem with the cement deteriorating (haze) but subsequent observations suggest that all of the LTM versions can exhibit haze.
It also appears that some copies do not have an issue with the cement. I have both versions, one has haze the other is clean. It may be an issue of batches, some used better cement, most didn't. Excellent lens though, even with haze.
