Voigtlander 15mm Heliar LTM Adapter help

Question for you all - just bought a Voigtlander 15mm LTM and attempting to use it on my M5. The only m39-m adapter that gets close to fitting it is my 28-90. Unfortunately it doesn’t screw all the way in.
Does anyone have any experience with these, will this affect the end result much? If so what is a better alternative for this?

Strange - I have had no problem at all with the Voigtlander made L39 to M adapter I bought, sits centrally and no bit jutting out like that. I'll have a look when I return home tomorrow afternoon.

I do all my own black and white developing at home.

Well, this is a 3rd party L39 to M adapter. I've never had an issue with any of them.

Voigtlander doesn't sell the adapters anymore, unfortunately. Hope to find another solution. I have a test roll in now. Will see the results later this week.

Does it thread onto the adapter off of the camera? Try that just to rule out the possibility of threads on the lens or adapter being boogered up.

No - the way it is in the picture is the maximum it'll screw on, on or off the camera.

I ponied up and bought a Leica one when I had M5. Worked great with the 15 and it was great to have metering through that lens.

You won't experience any problems. Mine looks the same with an original voigtländer adapter. There was a tutorial somewhere on the net on how to adjust the lens but it is not necessary.

Honestly it was a long time ago. I had all of them at the time. Perhaps somebody that has gone the same route as I can better answer that.

It's not coupling to the rangefinder, so would any of them work as well???

C'mon Yall!

Do you mean that doesn't align properly, the top of the lens doesn't point to the top of the camera? That's normal and inconsequential, as long as the adapter is screwed all the way on.

It doesn't line up at 12:00 that's normal. Is that you issue?
Shoot some test film and make sure it's OK before proceeding any further.

The center is off slightly, but the lens will still work properly; this particular lens does not couple to the RF. Regardless, zone focusing works just fine on a lens this wise (even wide-open).

From my experience, you need a 50mm ltm->m adapter for this lens. Another adapter will not align the hood at center position, that will cost some blockage from the hood.

The "focal length" of the adapter doesn't matter, QC does. Leica adapters are best, Voigtlander are excellent, cheap ones have less than stellar QC which can leave coarse threads and a variable entrance point for the thread.

It's an ultrawide lens, so the misaligned hood position can affected to the image.

My best advice...sell the LTM and buy, either the CV M 15mm II or III. You'll get much better results with these two lenses.

Neither newer version of the CV15mm are anything like as small. I think i'm correct in saying Version II optics are the same as the first version.

Yes, which is why the quality control of the LTM adapter production needs to be taken in to account. Get a cheap adapter, your lens may be misaligned.

Not as small. This said, I amend my post and will attest that the CV 15mm III is way superior to it's predecessors. I use it a lot, paired with the CV 15-35 Zoom Finder and it's a great package, on my Epson R-D1's and Leica's.

I don't see how that is possible. If the lens won't seat fully, the distance to the film plane has got to be wrong.

To the OP: 1. Does the lens seat fully into an LTM body? 2. Do other LTM lenses seat fully into the adapter?

Some CV lenses have several screw holes for the mounting flange, maybe this is one of them. If so, the flange can be mounted a few degrees away from how it is now, I think these extra holes are there for the reason that this happens.

Just back and tested it out - the lens mounts properly with the Voigtlander 28-90 and with my genuine Leica 35mm adapter. It is out with a cheapo (rikon?) and a Leica fake. Also my M42 to QBM, but that was a mistake.

Interesting. I have the original 15mm lens and with the Voigtlander 35/135 adapter the lens doesn't quite make it to the white dot at 0 degrees. It's a little bit to the left ( 355-ish degrees ). With a no brand 50 adapter it's past 0 degrees--a little < 5 degrees.

My 35mm Color Skopar on the 35/135 adapter is about the same as the 15. Same for the no name adapter.
