Multi-layer sensor splits light bands for more accurate color representation
Sigma has unveiled the first of a trio of compact cameras with vertical color separation technology. The dp Quattro collection all use the Foveon X3 "Quattro" image sensor, one which uses three layers of photodiodes assigned to each RGB color, with the manufacturer claiming it allows the camera to capture the hue, value, and chroma for each pixel more accurately than the mosaic-style sensors used in other cameras.
Aside from the 39MP-equivalent sensor, it uses a True III image processor designed specifically to work with the sensor. Offering a sensitivity of between ISO 100 and ISO 6400, the dp Quattro range includes 11 different color modes, a nine-point autofocus with contrast detection AF and face detection modes, and a shutter speed between 1/2000 of a second and 30 seconds.

While the internals are impressive, it also includes a striking external design that the company states "offers a balanced shape, layout, and weight distribution." The thin and wide body appears to lack any major complexity typically associated with a high-end camera, but it still offers a typical 3-inch, 920,000-pixel display on the rear, an SD card slot, and USB connectivity. The first camera launched, the dp2 Quattro, has a 30mm f/2.8 lens offering a 35mm equivalent focal length of 45mm and a manual focus ring, while the dp1 and dp3 will offer a 19mm wide-angle version and 50mm telephoto lenses respectively when they are launched.
Sigma has yet to reveal the release date nor the price of the dp2 Quattro, but the entire range will probably have a fairly high price tag attached when they ship.
