PhotographyBlog published a review of the Sigma DP1 camera.

Quote from the review: "The Sigma DP1 is the first ever compact digital camera to feature a large image sensor typically used by much bigger and heavier DSLR cameras. Sigma have taken the 14.03 megapixel X3F sensor from their SD14 camera and designed the DP1 around it. Weighing less than 250gms and easily fitting into a coat pocket or handbag, the DP1 promises to deliver DSLR-like photos in a portable, carry-everywhere design.
Sigma have twinned the sensor with a fixed focal length 28mm lens, further appealing to the serious photographer who demands the best image quality possible from their equipment. We find out if the Sigma DP1 has been worth the long wait since it was first announced way back in September 2006."
