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='

It used to be like this in most cases (see the results for Zeiss 16-35 for example) but apparently with some lenses the bigger pixel density of modern DX sensors becomes lethal. Odd it should be this way, of course, but the manufacturers chose to race ahead with more megapixels, and while the new technology is doing better for noise performance, it's apparently killing many otherwise fine lenses by overstretching their resolution capabilities. Catch 22 indeed.
