Sigma DP2 review
There are several features of the DP2's specification that mean that image quality is pretty impressive in general. The combination of the large Foveon sensor and fixed focal length lens mean that image flaws should be kept to a minimum, and that is very much the case. Noise is well controlled up to the maximum ISO 800 in jpeg, and continuing to be reasonably non-intrusive right up to the maximum ISO 3200 in raw. The dynamic range displayed is also impressive, with detail well maintained in both highlight and shadow areas. Images are short out of the camera, with little or no barrel distortion of fringing. Colours appear pleasingly natural, if a little flat, while exposures are more often than not correct.
