I agree with Christian - imho optical rating should represent how lens behaves wide open. After all we pay hefty premium for larger aperture, not for ability to stop down. Also I find the logic "Zeiss gives no image at all at f1.4" a bit flawed - in this case, for instance, 24mm f/2.8 shouldn't have received more than two stars, because compared to 24mm f/1.4 it can't take any pictures at f/1.4 and even at f/2, right?
