Klaus, wouldn't lighting be practically identical if you perform the test at noon on a bright day? You can also put all tested cameras one by the other on a horizontal bar (e.g. Manfrotto 131DDB), and perform the test at the same time and at what is practically the same angle. The subject of course would be the same too.

Best would be to not shoot on a bright day, but on an overcast day. This makes the lighting the most uniform and repeatable.

Also, you should perform the test a number of times per camera/lens combination, and middle the results.



You would need a track you can use, and a car which is easily set to a specific speed.



And that is only for a coming towards you-subject. You should also test cameras to track subjects moving irregularly across the frame and track with a very busy background and a smaller subject... The performance of AF tracking is very complex, and so is the testing of it.
