I guess the same arguments can be applied to FF vs medium format :-))

Agree... and medium vs. large, etc.

Sony A850/A900 and Nikon D3X have similar pixel density as 10/12 mpix APS-C cameras (D200/D300), so that's not exactly true.

That's the dpreview way of comparing things... pixel to pixel. If I want 30x20" prints that's what I'll produce whether I use an APS-C or a FF. So the dimensions of the reproductions stay the same but the FF image has less magnification and hence better SNR.

Obviosly the 2.25x difference in light gathering is not going to dissapear, however the point is that crop sensors are so good at the moment, that the main FF advantages are no longer "so obvious" in most of the situations.

Sure... all cameras are good and are capable producing images that weren't possible before. But still there are cameras out there that are better than others <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='

The appearance of lenses like 25mm f/0.95 doesn't help either :-)

So someone managed to hack a manual focus lens on to the FourThirds mount that's barely equivalent (still less than) a 50 1.8 on FF plus a whole lot of aberrations... big woof <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

I don't get this one, care to elaborate? There are tons of FF lenses that look really poor on high density FF sensors, while still can be used APS-C because of sweet spot.

Like I said before, it's not a fair comparison unless we're comparing at the same reproduction sizes. And the differences you can see will also depend on how large your print them. I'm sure there are exceptions such as when an APS-C lens has be re-badged as a FF lens (e.g. 70-200 VR), etc.
