Sigma has developed a new "Quattro" sensor for its latest range of compact cameras in the DP series.

Sigma developed a new generation of Foveon X3 direct image sensor, called Quattro, for use in its re-designed DP range of compact cameras. The Foveon is similar to colour film as its multiple layers capture all the information that visible light tansmits, Sigma says.

Sigma has also redesigned the engine, lens and body for its DP series. The new cameras use Sigma's proprietary image processing technology to produce "incredible resolution, precise gradation, gorgeous colour, breathtaking realism with a 3D feel. In other words, full-bodied image quality", Sigma says.

Sigma hasn't revealed much more in the way of specifics on the range. But it says: "The new-generation DP series embodies Sigma’s philosophy of creating cameras that produce works of art."

We'll have to wait and see if these bold claims prove true when we get a look at the first Sigma DP Quattro camera, hopefully soon.
