Imaging Resource has reviewed the $800 4.6 megapixel Sigma DP1.
Here’s what they thought:
“Thanks to its higher price of around $800 and the other limitations mentioned above, the Sigma DP1 doesn’t meet the needs of the general photographer wishing for an SLR replacement or substitute. However, the patient photographer might find the Sigma DP1 a refreshing pocket companion for wide-angle photography, and it would certainly serve well as an auxiliary wide-angle choice while shooting with a telephoto lens mounted on your SLR — if only it were a little faster. As with any photographic tool, an artist can make much of any device that can image as well as the Sigma DP1.”
