did you use mirror lock-up ?

No--I used a tripod with a flash. This should be very effective at eliminating any motion blur.

could you please post your shutter speed at each F stop, thanks for posting this test. Another interesting test would be to compare each shot with direct facing lights (not too close though) and no lighting coming from behind.

This is silly, tripod mounted with flash isn't it enough? You may argue with 500mm lens that's not enough and MLU should be employed. In that case just see the examples of 55mm, 105mm and 24mm. You may not answer me but please be modest if you do. I have no intention of engaging a reply war with you. Sorry if I offended you.
