Last weekend I had the chance to experiment with 33 megapixel Sigma DP2 Quattro in New Orleans, LA. This camera just recently started shipping. It wins the award for probably one of the funniest looking cameras to hit the market.......ever. Despite its funny look, it does have some incredible features as well as some serious quality.
Sigma cameras all include the Foveon X3 sensor. Most cameras are using the Complimentary Metal Oxide Semiconductor (CMOS) chip as their sensor. This particular Foveon design was built entirely different than Foveon has in the past. Basically Foveon layers up red, green, and blue and lets light strike every single photo site on the sensor. The effect is having every site used. With bayer array sensors such as CMOS, interpolation occurs making only about 1/3 of pixels actually used for capture. The rest includes data gathered by averaging whats next to them.
One of the most useful features, in my opinion, is the variety of aspect ratios available. The camera is able to photograph in 3:2, 4:3, 1:1 (square), and 21:9 (panos!)
Even though the 30mm lens is fixed, it is a normal lens and is a very sharp lens. It takes an incredibly sharp lens to effectively render 33 megapixels of resolution to the sensor. Sigma plans on making two other cameras, the DP1 Quattro (19mm lens) as well as the DP3 Quattro with a 50mm lens. In addition to the high resolution, the camera is without an anti aliasing filter making images super sharp straight out of the camera.
