If you look at the official Nikon MTF charts for the 28/1.8, there is a dent in the MTF curve, which is well within the DX frame. That dent is likely emphasized with higher frequencies. So, combined with demanding high resolution sensors, the quality-drop off is more pronounced than on the larger sensor with lower pixel density. I have some more lenses in the pipeline that show weaker performance on the D7000 than on the D3x (in the borders and corners). One of the is for example the AF-S 35/1.4.
I'm almost through with the CX review of the 28/1.8. On that very high density sensor, the lens struggles even more, even though it's a much smaller sensor.

And here I was, thinking FF lenses would perform better as sensor gets smaller because it will only use the best part of the lens - the center. Silly me.... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='
