I'm currently a 5D and an aging(both me and camera D100 user. The Sigma slr's have intrigued me so I was very interested to hear about the DP1 coming to market. It sounds like a good way to check out the foveon sensor as well as seeing how well Sigma gets it done. If I find I like the results obtainable with the DP1 then maybe I would consider the SD14 as a replacement for the Nikon. My Canon 5D is a superb camera coupled with L lenses so it would take one heck of a camera to replace that!
