That could only mean that Sigma copied the hole protocol and message fields from the Canon-EF to use in there own SA-mount electrical interface.

Or is there a protocol converter, small integrated circuit on a board, built somewhere?

The lens that I mention have green cast problem, I'm not so expert in post production, I can't correct color.

Now I can't compare because of my 8-16 in SA mount. From my feeling tokina give brighter picture and a little bit sharper.
