Compact cameras have a tough time standing out these days, but Sigmas new dp Quattro range has definitely succeeded with its unconventional design. Running against the current trend of retro aesthetics, the dp Quattro trims away any and all excess from the body, resulting in a squat, stretched-out shape that emphasizes the primacy of the lens and the hand grip. Beyond the sharp new look, Sigmas trio of new cameras differentiate themselves with the use of the companys proprietary Foveon X3 Quattro image sensor — with a separate layer for each of the RGB colors — which is touted as delivering medium format-level image quality anywhere, anytime. The actual sensor inside the dp Quattro cameras is of course not quite that big, but at 23.5mm x 15.7mm its comfortably larger than the usual fare youd get in a shooter of this size.
