Sigma DP2 Quattro Review

Image Quality


All of the sample images in this review were taken using the Super-high JPEG setting, which gives an average image size of around 25Mb.

The Sigma DP2 Quattro's image quality is outstanding when shooting in the RAW format, with great results from ISO 100-1600. Curiously the quality drops off noticeably when shooting JPEGs, with only ISO 100-400 worth using thanks to a lot of noise and colour desaturaion at the higher ISOs, so our advice would be to always use the DP2 Quattro's RAW mode if possible (despite the so-so Sigma Photo pro software and the huge file sizes).

The Sigma DP2 Quattro dealt with chromatic aberrations so well that we struggled to find a single example from the hundreds of frames that we shot. The images were just a little soft straight out of the camera at the default sharpening setting, but you can increase the level in-camera, or use Adobe Photoshop later. The night photograph was very good, with the maximum shutter speed of 30 seconds allowing you to capture enough light for the majority of after-dark situations. Macro performance was the only fly in the ointment, only allowing you to focus as close as 28cms away from the subject.

Noise

There are 7 ISO settings available on the Sigma DP2 Quattro for both JPEGs and RAW files. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and RAW on the right:

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The images are just a little soft at the default sharpening setting of 0. You can change the in-camera sharpening level to one of the 10 preset preset levels (0.2 increments on a scale of +1 to -1) if you don't like the default look.

File Quality

The Sigma DP2 Quattro has 3 different JPEG image quality settings available, with Fine being the highest quality option. Here are some 100% crops which show the quality of the various options, with the file size shown in brackets.

Fine (21.2Mb) (100% Crop) Normal (11.35Mb) (100% Crop)
   
Basic (9.27Mb) (100% Crop) RAW (53.1Mb) (100% Crop)

Chromatic Aberrations

The Sigma DP2 Quattro handled chromatic aberrations so well during the review that we struggled to find a single example to show you. You won't notice any chromatic aberrations in almost all photos from the DP2 Quattro.

Macro

The Sigma DP2 Quattro doesn't offer a dedicated Macro setting. The closest distance that you can focus on a subject is 28cms away from the camera when it's set to Full Focus mode. The first image shows how close you can get to the subject (in this case a compact flash card). The second image is a 100% crop.

Night

The Sigma DP2 Quattro's maximum shutter speed is 30 seconds, which is good news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 30 seconds at ISO 100.
