This was a bit of a shocker to us as well: Kazuto Yamaki, Sigma's chief executive and lead design guru, doesn't want you to be distracted by the dp Quattro's strange shape. The extra-wide footprint is of course what first turned us on to this high-end camera, but the takeaway here should be the shooter's 29-megapixel Foveon X3 CMOS direct image sensor, which Yamaki says enables a reduced file size and better high-ISO performance.
