Sigma introduces the dp2 Quattro

On first impression the Sigma dp2 Quattro is not a typical compact camera. It has a slender body, with a prominant fixed lens and an unusual diagonal grip. It's design is not the only thing that makes this camera unique. it also features the latest incarnation of Sigma's Foveon X3 direct image sensor, which uses vertical color separation technology.

The dp2 Quattro is the first in Sigma's new line of fixed focal length cameras which prioritize image quality. A trio of dp Quattro compacts will feature either a wide-angle, standard, or medium telephoto lens. The dp2 will be the first to be released and is the standard focal length offering, with its 30-mm lens giving a 35-mm-format equivalent of 45-mm.

This vertical color separation allows the sensor to record hue, value, and chroma for each pixel. It also means no color filter or low pass filter is required, resulting in high-quality images with rich color detail. Presumably to allow for faster image processing, the top photodiodes layer of the new sensor is 20-megapixel, while the middle and bottom ones are 4.9-megapixel – in the DP Merrills, all three layers had the same resolution. RAW images will have a 5,424 x 3,616 (19.6-megapixel) resolution.

As mentioned, the Sigma dp2 Quattro will feature a standard 30-mm F2.8 lens (offering a 35-mm-format equivalent of 45-mm). It will be followed by the dp1 Quattro, with a 19-mm F2.8 lens (28-mm equivalent), and the dp3 Quattro with a 50-mm F2.8 (75-mm equivalent). All the dp Quattro cameras will also feature a new TRUE III image processing engine, which is designed to get the most out of the sensor and produce rich, detailed images.

The cameras will all have an ISO range of 100 to 6,400, and autofocus will be dealt with by a 9-point contrast-detection system, which is hopefully faster than that which hindered the DP Merrills. There will be the option to shoot 14-bit RAW and JPEG, but as with the Nikon Df, there's no movie recording.

Design-wise, the dp Quattro cameras feature the same body, though measuring 161.4 x 67 x 81.6 mm (6.4 x 2.6 x 3.2 inches), the dp2 will be the smallest, as the 19-mm and 50-mm lenses will be bigger. On the back, the cameras will have a 3-inch LCD with 920k dots and plenty of space for a minimalist button layout, while on top of the grip there will be two control dials.
