Sigma has announced the DP3 Merrill, the latest in its range of unusual fixed-lens compact cameras. The DP3 pairs a 50mm f/2.8 lens with Sigma's unique APS-C Foveon X3 sensor, which essentially stacks three 15.3-megapixel layers on top of each other; Sigma claims this equates to a 46-megapixel image, though in practice the resulting shots aren't necessarily comparable to more traditional cameras. Instead, they're known for their unique color rendering and high quality considering the cameras' small physical size.
The DP3 Merrill is the third camera in the series, and follows last year's 19mm DP1 Merrill and 30mm DP2 Merrill. Sigma now has a pretty solid lineup of advanced point-and-shoots — If you're up for buying whole new cameras instead of adding lenses to an existing body, that is. There's no word yet on pricing or release date, but the DP1 shipped for $999 last year.
