So Daniel, you've never used the D800 or the D3X? I have to say these are wonderful cameras. I can't get over the skin, hair, and fabric textures, around f/8, at web size.
So basically what you're saying is that if I didn't drive a formula 1 car, I can't really claim it won't beat a Ford Focus around town?
BTW you should see skin, hair, and fabric textures from Olympus E-1, on 1024x768 size. I could pass it as a digital Hasselblad to anyone. So yes, those are wonderful cameras but you can see a difference only if you print big. On screen or on a small print, almost everything can give them a run for their money.
