These cameras use the same sensor, so the differences should be less, and indeed they are, in a blind comparison it would be very difficult for anyone to pick one from the other. The only visible differences are a lack faint of moire artifacts on the D80 image, which we see in the DSLR-A100 image around black contrast (such as text or the Martini logo). But honestly none of this would be distinguishable.
