Ronny, why don't you compare the AF of your camera with his using the same lens. So, do the comparison under the same conditions and using the same "target". Since we are talking about native lenses here, I am sure yours will be able to AF OK. And if you guys find out that his is doing worse than yours, then you know for sure that there is something wrong with his. I assume that you guys are local from each other in this case.
If you are both using the same lens and camera, you may also want to swap lenses between you to run some further testing to see if you are getting the same or almost the same results as for the first comparison.
