This compares them head to head.
I have the D50.. I love it, but it was a Christmas gift so the comparison shopping was done by someone else. I trust his judgement and research skills like I trust Jack Bauer's.
One of the features that caught my attention on the D50 is the "Child" setting. Have you used this much? It's almost as if they're luring me to that camera with a magic setting that promises good shots of my wiggly kids! Some genius is marketing must have come up with that one!
Also, thanks for the link to the comparison. It is very helpful.
