Stay away from the Olympus digital SLRs because they use a smaller
sensor and are noisier.

Then why do the Olympus E510 examples look better than the Nikon D40X in
side by side comparison?

Agree that the Olympus looks better in the first shot - but
the difference could be the lens, or could be differences in
the level of sharpening.
Now go to the drop down list and choose "Barbie, detail
without flash". The Nikon is at ISO 3200, the Olympus is
only at ISO 800. Despite the ISO on the Nikon being 4x the
Olympus, they are about the same as far as noise. The Nikon
colouring looks better too.
