Doesn't that depend on which part of the 5MP frame you make the 2MP crop from, and the relative quality of the 2 lenses?
I would presume that if you crop from the centre of the 5MP frame, where the performance of the lens is expected to be the best, you might end up having less distortion than a full frame from a 2MP camera, provided that the 5MP lens has at least twice the resolvng power of the 2MP lens.
Erm, not really. There is a difference yes, but a decent lens should perform well enough to resolve 5mp equally well to the corners. The issue that I'm getting at is that if both the CCDs are the same physical size (which they usually are in consumer cameras), then the 2mp off a 5mp chip will be physically far smaller. Given that bigger CCDs enable better light gathering capabilities which in turn reduces noise, improves tonality etc, the image off the straight 2mp chip should be better. Which is the same reason why DSLRs with their relatively large CCDs still outperform consumer digicams.

There are pple who ask me why i downgrade from 5MP F707 to a 3MP D30
