Foveon X3 Pro, Sigma D10 and two new lens

According to Foveon, the maker of advanced Foveon X3 X3 Pro, Sigma announced its new SLR camera on this matrix Sigma SD10. Sigma hasn´t posted anything on its website yet, so we had to use external sources.

F7X3-C9110 (Foveon X3 PRO 10M) matrix is similar to Foveon 3: each photosensitive element features 3 photodetectors for red, green and blue colors. They are located on different depths in the silicon crystal utilizing the dispersive properties. The most shortwave blue color is consumed first, so the blue photodetector is the closest to the surface. Then there go green and red ones.

Comparing to the previous version, the new matrix features improved (doubled, according to the maker) sensivity range and longer expositions (up to 30s).
