Hi Kelly
I have 2 now and would consider letting one go.
Send me a PM when you get serious about it

I would be happy to make you an adapter if you need one.

I will need a flanged M42->PK adapter and an Exakta metal rear lens cap - actually I have a spare and I can give it to you.

I don't see why nobody produces exakta->"modern mount" adapters. I used slide gauge to make sure and it should be possible to produce at least exakta to Sigma SA adapter (infinity focus) - there should remain at least 0,5 mm space between exakta mount (Biotar) and SD14 dust filter...

Thanks Luis
Both of mine are m42.
One actually came from Attila and I will keep.
The only reason I would sell is because of need to buffer finances.
Duplicates in this lens are not necessary for me.

I am not actively looking for a buyer.
If someone here is serious I would consider it.
Otherwise there are many other lenses I will sell before this one for some extra funds.

[Katastrofo]

All excellent but the first says it all, congrats, Luis! For me it is down to the
two Z's: Zeiss and Zuiko!

[Attila]

[BobDodds]

We do not notice where or if important areas go out of focus. Graceful decay into oof, that is special with biotar 75/1.5, and Zeiss generally. But, 75/1.5 wide open, still having gradual inconspicuous decay into oof at wo, that is very rare.

[BobDodds]

According to my little paper gauge, Sigma SA ir-dust filter would touch Exakta mount.

I cut off three Exakta mounts to make them flush with M42 threads, and one was already cut off to make 1930's biotar 75/1.5 Exakta into M42. That was an ugly job, scratching lots of silver off to expose brass, ugh. I might do that one over. I am using M39-to-M42 rings, which come in brass or aluminum. Brass ones need grinding out of M39 slightly to fit.

The one caveat to M42 as universal interface to dslr adapters is that the focus and aperture scales probably won't match to top center without using paper washers and changing infinity focus. I only hit one out of three last night, and a fourth was already off by 90 degrees when I bought it. I learned a lot though.

[thePiRaTE!!]

I'd like to thank everyone for being so helpful and patient with regards to my request - I've learned more in a single post here than in months of poking around randomly on the web, I've also lit the fire under getting it done.

Luis, I appreciate the offer. Andy's kind offer to consider one of his M42 versions for sale might make things straight forward, but if I end up sourcing another, I'll certainly look forward to your assistance!

In the past 2 weeks, I've already made three acquisitions (one was Bobs Yashinon 55/1.2 - thanks! ) and sold another lens to cover those - I'll have so many new lenses to test when they all get here I'll be lost for a month... heaven?

Hi Bob,

How do you securely attach the M39 ring to the Exakta mount ?
