Sigma DP2M vs Sony NEX-5N comparison @ ISO 100, 400, 1600

A friend of mine just bought a Sony NEX-5N, so we performed
a comparison test between the two cameras at ISO settings 100,
400, and 1600. You can download the jpg-converted images at
the original size by clicking on "Original" next to the title of each

We used the Sony 18-55 Zoom and tried to match the focal length
of the Sigma DP2M as exactly as possible (we didn't succeed completely).
We shot from two tripods set very close to each other, so the view is
very similar, but there are slight differences.

We used Aperture priority mode at f/10 on both cameras, in order to
have good depth of field, without running to much into diffraction, and
set both cameras to produce RAW files. No output sharpening was
. If you want to maximize sharpness for both cameras, you
can download the original files, and perform sharpening yourself.
I recommend Unsharp Mask 100%, radius 0.3, threshold 0 for the
Sigma, and Unsharp Mask 200%, radius 0.3, threshold 0 for the Sony.

RAW files of the Sigma DP2M were processed with Sigma Photo Pro with
only the following settings changed from default: Shaprness -2.0,
chroma noise reduction 3/5, luminance noise reduction 3/5.

RAW files of the Sony NEX-5N were processed with Photoshop 5.5 and
all default settings for the camera.

In the hope, that this helps you evaluate the Sigma DP2M,

PS: The timestamps of the photos do not match, since the
cameras were set to different time zones.
