Hi there,

I've found several posts here about Pentax to EOS adapters.
It seems to me these posts don't have a straightforward solution, meaning sometimes users need to remove the lever from the lens or do other tricks in order to get the lens working.
So, I've just seen a couple of adapters on Amazon, one of which seems to have good reviews. I'd love to hear your thoughts.

I have a few, but all mine are not as good as the opinions. They are ok with canon crop sensor bodies, but not as good on 5d/5dm2.
In the end, i got sony a7r to use pentax glasses on FF.

Pentax to EOS adapter doesn't have anything to do with compatibility on 5D. It's the lens that doesn't fit. Either have to remove or file the aperture pin.
I have two pentax to eos adapters and with both the lens is rotated to left when mounted. This is anoying because pentax A 200mm f4 has a square baffle in the rear that causes vignetting.
Anybody knows cheap ebay adaptors that will fit the lens at a proper position?

You can mod the adapter to the proper position if you cannot found one.
