Sigma's got the DP2 burning up retinas, so we're not entirely sure why they're reheating the older DP1 in the form of the DP1s. It's got the same Foveon X3 sensor, but pulls some features from the DP2. Exciting. [DPReview]
What a piece of crap. I had the DP1 and it was one of the slowest focusing cameras in the world.
Now I have the Panasonic GF1. Now THAT'S a real camera. Sigma had the market to themselves and could have corner it but they really screwed the pooch by releasing a camera that performed like it was from 1999!
