Sigma's SD1 Merrill Digital SLR Camera is the company's SD1 DSLR, renamed to honor the great Richard "Dick" Merrill, the co-creator of Foveon X3 Direct Image Sensor technology. The most outstanding feature of the SD1 Merrill is this APS-C sized X3 CMOS sensor, which uses three layers of 4800 x 3200 pixels to produce a 46MP full color sensor. Using the True II image processing software, the SD1 Merrill delivers high-resolution images processed quickly with high definition and a smooth and subtle graduation of color.
