Sigma DP-2 first look

I’ve been shooting the Sigma DP-2 and I’ll have a review in DAP sometime soon, where I’ll cover ergonomics and usability, image quality, etc.

Although the DP-2 generates only a 4.6-megapixel file (2640 X 1760), the detail provided by its sensor is pretty incredible. You won’t get anything nearly this clean from a conventional DSLR. The crop below is actual-pixels.

Actual pixels. Note the incredibly fine artifact-free detail

Color rendition with the DP-2 something I haven’t figured out how to process satisfactorily yet (using RAW in Sigma Photo Pro), I do think color rendition is a weakness of the DP-2, though there is some possibility that I might yet hit upon processing parameters to result in the color I’m expecting.

The image below is a torture test; it’s an extremely saturated red wall in real life— red hot and way beyond fire-engine red. The DP-2 could not capture it properly. Even so, it’s massively out of gamut in sRGB, so it’s shown here in AdobeRGB; you’ll need a color-aware browser to see it properly, and even then it’s very likely that your monitor can’t even display the color. The NEC 30" LCD 3090WQXi can display great differentiation in the reds however, much superior to the Apple 30" Cinema Display.
