Hi, i´m looking for a contax (IIa) to leica screw mount m39 adapter.

I found easily on ebay the kipon branded one.

My question is if this adapter performs well when lens is wide open.
I´ve read that nikon and contax distance to film to flange are slightly different and therefore can be used at f4 and down (inaccurate WO)
Looked on ebay and are listed some adapters that say only contax II/III, does it means that this ones are exclusively for contax lenses?
The letter A means that i must look for a exc. Contax IIA adapter??

Any experience on this kipon only adapters?
I would buy an amedeo but can´t find for M39, just M mount!

Thanks!
 
Amedeo told me he had m39 adapters. I have them both for Leica M.
Contax/Nikon adapters have lens compatibility issues, not allowing mounting all the lenses. Review another threads in this forum.
The difference in the helicoid between Contax/Nikon is more relevant for 50mm or longer.
Best regards,
Juan
 
Yes, Amedeo makes a Contax to LTM. It will focus correctly at any aperture as long as you put a Contax RF lens on it. This is a photo of his adapter with a Carl Zeiss Opton Sonnar 50/1.5.

If you have Nikon RF lenses, get Amedeo's Nikon to LTM adapter.

You may have to adjust the lens for best performance wide-open and close-up. That is what I did for my Amedeo Contax to LTM adapter: used the adjustable ring of the optics module of the post-war Zeiss 50mm F1.5 to fine-tune for close-up and wide-open.

None of the adapters use an "index-Cam" to correct for the slight difference between the Contax and Leica standard. I have an M-Mount adapter that was custom made, with the cut made into the cam to allow for near and far focus.
 
Hi folks, thanks for your answers very helpful!!

I contacted Amedeo to ask for his ltm adapters, hope he has in stock!

Thanks Brian, i love reshimming and adjusting!!!!

Best regards!
 
Hi!, love it!!!

The most enjoyable thing it´s the small size of the lens!!!
Can´t find nothing comparable!

thanks!
