Best EXA-EOS adapter !

Orio · Expire: 2012-12-04

I have just received an EXA-EOS adapter that I bought from seller cam.plus in Hong Kong:

http://myworld.ebay.it/cam.plus/

It has FA chip, it reaches infinity focus no problem, and most of all, it locks lens perfectly! Not only better than my previous exa-eos adapter (which did not lock at all), but also better than any other bayonet adapter I have ever used.

It is not cheap, but it is an absolutely recommended purchase if you own an Exakta lens that you treasure.
From not on, this adapter is sitting permanently on my Biotar 75 Very Happy

Got it. Sorry Orio. Works probably only with German lenses. Doesn't work with Angenieux, Komura, Kilfitt. Mirror issue

Orio
I looked at this adapter and I do not believe that it will accept Topcor lenses. Topcor RE Auto lenses have a pin to advise the camera of the chosen aperture that sits approximately 2,5mm from the edge of the mount. There is no corresponding groove on this adapter. I recently returned a very similar adapter for this reason

I tried lenses as follow:
1/ Komura 2.3/135
2/ Kilfitt Makro Killar D 2.8/45
3/ Angenieux 1.8/90 Type P1
4/ Angenieux 2.5/35 Retrofocus Type R1
5/ Angenieux 3.5/135 Type Y2
Adapter with above lenses doesn't work, all pins are removed from the mount of the lenses.
Adapter works with lenses:
1/ Tessar 2.8/50
2/ Biotar (chrome -black) 2/5.8cm
3/ Sonnar Olympia 2.8/180 (my guess this is copy of Olympia - the same details compare to this one Click here to see on Ebay except design of tripod mount and focal length - mine is in mm

Ok Voytek but what you mean with "works"?
Because one thing is what Patrick wrote (about the adapter not having the correct shape to mount Topcon lenses)
and another thing is what you write, because if you removed all the pins, making the back of lens able to mount the adapter, if the lens does not clear the mirror, it can not be the fault of the adapter, because if the adapter somehow was the cause, then no lens would clear the mirror with that adapter on. Instead, some lenses do. Therefore, simple logic says that the clearing issue is due to the shape of those lenses which don't clear, not to the adapter which is a common denominator for all the lenses (those that clear mirror and those that don't)

"works" means in this situation that adapter allows to work without any problems. Doesn't. This is not your fault. This is not "lens fault" regardless any kind of mount shape. All those lens which I pointed in my previous posts are working perfect with Exacta cameras. The only issue regarding entire situation is the auction description, not at all your post that this is a high quality adapter. AF Confirm EXAKTA / Topcon Lens to Canon EOS EF Adapter gives clear information. This information is not 100% true. There is not single warning about exceptions.

The second and third pictures in this link show the pin referred to above on the Topcor lenses very clearly:

Orio,

well either it is a different design or simply out of a batch of bad ones. This happens a lot in series production. They make 50 or 100 or so at one time and when nearly sold make another batch. Then they often forget to make quality check for the second batch and these might be off fractions of milimeters....
