I don't have a 5D III to check, but the 1dsii has a switch in the mount at about the 10 o' clock position that my chipped K mount adapter was a little too short to switch causing it to not work right. My other bodies did not have the switch and worked OK. I don't know if it has the switch, but it may be worth a look. I soldered a little extra to the adapter to make it work on mine.

That might be the issue others are having with chipped adapters.  I added a dandelion focus confirm chip to my Samyang 14mm (no adapter), and it works just fine.  However in the instructions it says you may need to drill a hole and insert a wire at a certain point to enable a switch.  Thankfully my lens already had that.
