Higher spatial frequencies usually produce worse graphs. I don't understand why they have used non-standard 20/60 LPMM test frequencies as it makes comparisons to other system difficult. What is interesting however is that even at 20LPMM the graphs show lower than average contrast for the Macro lens at least is is however very consistent across the image circle and shows very low geometric distortion. I wouldn't say that the MTFs are overall impressive though.
