Sigma SD9 Digital Camera

The breakthrough Sigma SD9 camera with FOVEON X3 image sensor is the world's first image-sensor that features three layers of photo detectors. The layers are embedded in silicon to take advantage of the fact that red, green and blue light penetrate silicon to different depths allowing full-color to be measured at every pixel. The layers are positioned to take advantage of the fact that silicon absorbs different colors of light at different depths, so one layer records red, another layer records green and the other layer records blue, This means that for every pixel on a FOVEON X3 image sensor, there's actually a stack of three photo detectors, forming the first and only full-color capture system. With the RAW data recording system of the SIGMA SD9 it is possible to obtain high picture definition and compact file size. Lossless compression system of RAW data, eliminates image deterioration, provides superior pictures without sacrificing original image quality, RAW data is convertible into high TIFF and JPEG formats by dedicated image processing software "SIGMA Photo Pro".

Depending on the intention of the photographer, the SIGMA SD9 allows photographers to select the resolutions of RAW data images in one of three resolutions, HI mode delivers highest resolution image performance with (2263x1512 pixels) x 3. MED mode (1134x756 pixels) x 3 has high definition and recording capacity. LOW mode (756x504 pixels) x3 allows consecutive shooting. The SIGMA SD9 is equipped with a large 1.8' 130, 000 dot low temperature polysilicon TFT-LCD monitor with white LED on the back panel, which displays images, menus and histogram, The coverage area of the LCD monitor is 100%, and it will have similar coverage to that seen from the viewfinder and thanks to the LCD-monitor, the composition can also be seen easily. The SIGMA SD9 can transmit the images from camera to computer with high-speed IEEE1394 (S400) and widely available USB interfaces. SIGMA SD9 employs CF card as Image Storage Media. Since the SIGMA SD9 is compatible with the Compact Flash Type II card, use of IBM Microdrive is also possible. The outstanding storage capacity of IBM Microdrive enables photographers to use the camera even more effectively. Two CR123A batteries, which are located in the grip part of a camera, are used as a power supply for the camera drive part. In addition, two CR-V3 lithium batteries located in the lower part of the camera, are used as a power supply for the digital parts, such as a display of LCD, and image processing lithium batteries enable photographers to shoot many images.
