Well, I was about to thank you there, Klaus, and now I'm unclear again..! Thanks Popo! <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='

It's a bit like the answer I was trying to get to [url="http://forum.photozone.de/index.php?/topic/745-d7000-lens-tests-implications-of-high-mp-density-sensor-on-lens-choices/page__p__6681__fromsearch__1#entry6681"]here[/url] a while ago

A lens will not be decentered more, nor will there be more chromatic aberration or diffraction. There will only be more detail captured, also of afore mentioned optical mishaps.
You won't notice a thing, with higher pixel counts, when you print at the same size. Unless you print at such big sizes that the lower pixel count image will show its resolution deficiency. In other words: You will only see an increase in lens softness, CA or diffraction when the lower res. image starts to show you its pixels. And then, the lower res, image will always be the least attractive one!
Even noise wise, increased pixel density is not detrimental. It may well be that on pixel level one can measure a "louder" noise level, but the wrongly coloured pixel also shrink in size. Same sized prints will not show worse noise.
It is pixel peepers who think that increasing pixel density/sensor resolution is something bad. But they have been saying so since when the top digital cameras were only 3mp. They said it when DSLRs were 6 and 8 mp, and they say it now when we have APS-C DSLRs with 16 and 18 mp. Truth is, the 16 and 18mp APS-C DSLRs perform quite a bit better, detail wise and noise at higher ISO settings wise, than the 6 and 8 mp DSLRs from 6 years ago.
