Best method to couple Paxette (L39) to Nex

[JohnBar]

Looking for the best method to attach a SM Quinar 3.5/85mm to Nex

I am thinking L39/M42 then M42 helicoid - but is there a preferred solution?

also I hear there are adapters to EOS but I dont seem to see any.

Is your lens for a Paxette rangefinder camera? If so, it will have its own focusing mount, which is good, but will have a register distance longer than a Leica rangefinder camera. In that case, you'll need a short extension tube (can't recall the thickness, but Googling will turn it up for you) plus a Nex to L39 adapter.

Going for a helicoid will almost certainly mean you won't be able to get back to infinity.

Assuming you have a Paxette lens with B39 thread.

You cant buy an off the shelf adapter.

I made an adapter from a L39 adapter with a removeable ring. I put a small extension tube on the adapter to make it up to 44mm then glued the L39 mount inside it. It works just fine although to be honest the lenses are hardly worth the trouble.

Mine now acts as as an extension tube for my Jupiter 8.

You can use a Zenit 39mm adapter (or M42) but that pushes the lens a little too far forward and infinity is lost.

If you live in the UK and have a L39 adapter with removeable ring I can make one for you.

Either with short M42 to NEX adapter + M39 to M42 adapter or M39/LTM to NEX adapter with tubes/helicoids/bellows etc.. If you can access a lathe, it should quiet easy to make one from a M42 to NEX adapter with a mounting ring from a L39 to NEX adapter.

This helicoid will probably do the job. Click here to see on Ebay

A perfect extension tube for when you decide the Quinar isnt worth it.

Maybe this would be a possibility, not the cheapest, but the fastest interchangeable way to bring the Braun Paxette lenses to a NEX oder A7 !





you can find it in the sticky "VNEX" thread on page 3...

Or with the new VµFT Version also on Fuji or µFT cams

And clearly not only Braun Paxette are adaptable, also enlarger lenses with register distance above ~42mm

Hi Henry

Yes I had forgotten about the beautiful VNex system. Sadly I have already ordered a helicoid

[philslizzy]

Hmm got my helicoid its about 1.5mm too long for the B39 lenses - bummer. I can use it for my enlarger lenses and as an extra M42 adapter so not all is lost. I think a shorter adapter and a very thin M42 extension tube if you want to go this way.



My adapter is made from 2 sets extension tubes, the camera fitting is NEX the lens fitting is M42. I screwed them together, which made it too short then unscrewed each piece separately until the desired distance was achieved. I ran glue into the open threads to lock it all together. Then a nasty silver paint job. Scruffy but it works.

By the way the helical is an extremely well made bit of kit, it has a double helical so the lens does not rotate. Not bad for just under £20 post paid.

Or you can look for the vintage adapter

I have that lens, nice Little Cooke triplet.

Do you know the meaning of the -E- designation in the Paxette series of lenses.

Does it means Economy or something entirely different?

[philslizzy]

[Nordentro]

E means coupled if I don`t remember wrong

[philslizzy]

Correct, when writing the above I remembered there were other letters than E used. Here is my little collection with E (coupled), C and R both uncoupled.



I haven't a clue what the C and R mean.

[Nordentro]

C is probably Coated
