Sigma is turning camera development on its head by developing a camera specifically to take full advantage of the Global Vision lens series with the release of the sd Quattro H Mirrorless Digital Camera with a Sigma SA lens mount. This camera offers the utmost in resolution with a 44.8MP APS-H Foveon X3 Quattro CMOS sensor that uses a unique stacked design to deliver full color information at every single pixel without interpolation. By using a 1:1:4 RGB pixel ratio with a layered design, this eliminates the need for an optical low-pass filter, the sd Quattro H can create 25.5MP lossless compressed raw images with a spatial resolution equivalent to, and with richer colors, than that of a 51MP Bayer sensor. These vast quantities of image data are handled quickly and efficiently thanks to a Dual TRUE III image processing engine. Additionally, the relatively unique APS-H size provides a 1.3x crop factor when compared to a full-frame 35mm sensor.
