Sigma's SD1 Merrill DSLR 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. RAW file sizes range up to 45MB. These impressive features are housed in a lightweight weather-resistant solid magnesium-alloy body built to take the bumps and shocks of the real world. A pentaprism viewfinder and a high-resolution (460,000 dots) LCD monitor give you options for composing, focusing and reviewing your images.
A panoply of features include shutter speeds up to 1/8000 sec., seven different color modes, continuous shooting at up to 6 fps, a built-in pop-up flash, and sensitivity up to 6400 ISO. The SD1 Merrill has a 1.5x crop factor (compared to 35 mm or full-frame cameras). Sigma SA mount lenses are compatible with the SD1 Merrill.
