Thank you for your information.
So I understoof Michel Thobys test right.
This could be in my focus, becaus the Tokina gives you a lot of advantage on a 5D.
Think the focus, or better DOF, is not a problem at all.
A FF has lesser DOF than a Crop- but the Tokina should have sufficent DOF to get objects sharp from 30cm to infinity.
