You need to file the external pin if you use an EXA->EOS adapter(make sure you get one with a circular slot at the center of the adapter). I am not sure if it will interfere the mirror on a 5D3.

The seller's listing:
Quote:
Compatible:
Lens: Exakta Mount Lenses
Camera: Canon EOS Camera, may not fit 650D, 5d MARK iii

So who knows if there will be issues on your 5DIII's mirror.
On a side note, sounds like a great reason to get an A7 series camera. Twisted Evil

It is not the adapter problem which make it does not fit a EOS FF, the problem is on the lens side. Wink

Here's another option: http://www.ebay.com/itm/181713472473

I have this on my Topcor 135. No troubles on the 6D.
