Hello Klaus,
when you did the LoCA test, you state the AF was off. Now, for real world situations when AF is on, I presume that Canon has implemented some kind of correction algorithm (presumably like in the 50mm f1.2) in their AF software. You state there was an effect even at moderate distances, which I presume means it wasn't properly corrected. Have you done a LoCA series with AF, to see how far off it is? It might be nice to add a few more words to the review in this regard.
