I would have expected to see a drop from f/5.6 onwards due to diffraction. If it was a good lens, I would have expected f/4 to even be diffraction limited.

[/quote] They evaluate sharpness for A3 print size (254 DPI); according to Imatest, it is enough about 1755 LW/PH (MTF50) to get excellent print of that size (kit lens borders quality <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />).
