Pre-PMA 2002: Sigma's new SD9 D-SLR will be the first digital camera to utilize Foveon's recently announced X3 sensor technology. This new camera has a 3.43 megapixel (effective) X3 sensor which outputs 2268 x 1512 x 3 pixels. Each pixel is 9 microns which makes the sensor 20.7 x 13.8 mm (a 1.7x focal length multiplier). The SD9 has a Sigma lens mount and a unique dust protector just behind the lens mount to stop dust from attaching itself to the sensor. Price is expected to be around US$3,000.
