Here's another Galaxy S II post comparing the cameras of the Galaxy S II camera's against the rest.

The bottom line? The Galaxy S II camera is among the choicest of smartphone cameras. It has excellent colour reproduction and very crisp images especially at 8MP.

Arguably, the N8 offers a crisper image, though a slight edge goes to the S II for accurate colour reproduction. I'd give the nod to the N8, though the S II isn't far behind at all -- it's a game of inches.
