Leica LTM Matching the look of the Voigtlander 35mm Ultron 1.7 LTM in M mount?

Leica M39 screw mount bodies/lenses
I was using "close match" in the Leica 6-bit coding chart to match a Jupiter 35mm. The photos were dark and murky until I turned off lens matching. I think it can sometimes work.
 
Why not just pick up the LTM version, put an adapter on it. I did, it's great- and can use it on my LTM cameras.
The Black version has a better feel to it than the chrome version.
 
The ltm version of this lens was my target for a while, but then I told myself "I have many excellent 35mm lenses", so I did not get such a lens.

This is very disappointing, and I'm wondering if its possible or financially viable to get the lens elements rehoused. The look and rendering of the that Ultron is one of my favourites out of all the Voigtlander lenses I've used, and the barrel size and shape feels just right. Mine already has a very slight haze, and I recall that the elements are glued together in a way that makes disassembly and cleaning very difficult.

As far as the M mount version goes, it seems to have a completely different optical design, and is similar only in name.

I think it's the optical cement (was told that by a repair shop). Thus very expensive, if at all possible, to fix.
It's possible not all are affected, we've had a survey on the forum, some are apparently free of fog. But I've given up finding one.
 
Sorry for the naive question, specially in a forum like RFF so full of experts but how do you check for haze? I have this lens, was my first CV lens on my first RF acmera, the CV Bessa R.
Thanks in advance for suggestions!

Flashlight and look from different angles?

Only the first version. The second ltm-version has a different focusing ring, so it is easy to tell them apart (the first version has a more "flat" scalloping). I have this lens for about twenty years and there is no haze whatsoever. Great lens.

I think the 2015 Ultron M does not use the same optical design as the 1999 Ultron LTM version. Both are discontinued (according to the head bartender's notes). My LTM has a slight bit of haze most noticeable with a strong light source in the periphery, creating veiling flare. My early Summitar which also has some haze does something similar with a direct light source. Otherwise, wonderful rendering characteristics on both though, probably helped by the haze... (?)

Well, I have a Bessa R, and my original thought was to acquire a 15-28- 35-50-90 lens set, but

- the 35mm, from any manufacturer, is becoming next to impossible to find, going for US$ 700+ and pay VAT + customs for every lens coming from Japan, where they all seem to reside now
- a Summaron, which is vastly inferior to any modern 35mm and also inferior to the Ultron, costs almost the same
- the 15mm and 28mm Voigtlander are uncoupled from the rangefinder, and image quality of the new ones is at least as good
- 28mm are all in Japan so VAT + customs

so I'm giving up and getting a Zeiss Ikon ZM, and use the LTM lenses I've already got with adapters, plus VM versions for the ones I'm missing. That's why I was asking about a lens that had the same colors of the old 35mm.

The LTM 28mm Voigtlander lenses are coupled for the full range of focus if the rangefinder allows (most LTM cameras drop rangefinder coupling between the 70cm minimum focus and 85cm/90cm or so).

The LTM 15mm is uncoupled... but who needs rangefinder coupling on a 15mm f/4.5?! Even wide-open the depth of field is so big everything from 1m to infinity is in focus. It's basically just point-and-shoot.
 
Even though I favored the 50mm lenses over the 35mm lenses, I managed to buy quite a few 35mm lenses. I used them all. I really enjoyed trying out many lenses over the past years,. Among my favorites are:
1. Summicron 35/2 V1 M
2. Canon 35/2 and 35/1.5 LTM
3. Zeiss 35/2 M.

The Canon 35/1.5 became slowly a favorite after it stayed hidden in my closet for years.
I do not have any Nikkor or CV 35mm lenses.

You are correct, the 28mm are coupled - don't know where I got that notion!
The new CV 15mm is coupled though.
