Now here is an honest review of the DP2 Merrill..

Eugene is a smart guy, but you wonder if he's got a chip on his shoulder. The first comment about the Bayer blur seems to be a dig—and coming with someone with his background, he's not too stupid to realize the differences in the technologies. Overall, the camera occasionally delights him but lets him down at other times. My guess is that maybe he'd find some more satisfaction learning to work on his photography skills, and less worrying about equipment.

In other words (as my pal Laurence is fond of saying), learn how to get the most out of your camera. Even if it's something other than a Sigma.
