| The breakthrough Sigma SD9 camera with a Foveon X3 image sensor is the world’s first image-sensor that features three layers of photodetectors (most digital cameras only feature one). |
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-colour to be measured at every pixel. The layers are positioned to take advantage of the fact that silicon absorbs different colours 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 photodetectors, forming the first and only full-colour capture system. | | The SD9, powered by Foveon X3 image sensors captures red, green and blue light at each and every pixel. All other image sensors feature just one layer of photodetectors, with just one photodetector per pixel. To capture colour, pixels are organized in a grid, or mosaic, resembling a three-color checkerboard. Each pixel capture just one colour-red, green or blue. The filters let only one wavelength of light (red, green or blue) pass through to any given pixel, allowing it to record only one colour. As a result, mosaic sensors capture only 25% of the red and blue light, and just 50% of the green. | | RAW Image Format | With the RAW data recording system of the SD9, it is possible to obtain high picture definition and compact file size. The lossless compression system of RAW data, eliminates image deterioration, and provides superior pictures, without sacrificing the original image quality. | | Image Recording With Three Resolution Settings | Depending on your intention for the output results of, the SD9 allows photographers to select the resolution of RAW data images in one of three resolutions: | | Hi mode delivers highest resolution image performance with (2268x1512 pixels) x 3 | MED mode has high definition and recording capacity | LOW mode allows consecutive shooting | | Sports Finder | The coverage of a viewfinder of a digital SLR camera with interchangeable lens is almost the same as the picture seen on its image sensor. However, the coverage of viewfinder can be maximum 100%, and no portions of the outside area projected on the image sensor can be seen. The SD9 is equipped with a "sport finder" for easily following the situation outside the picture area. The area that is out of the image sensor coverage range is marked by transparent light gray, to distinguish it from the active picture taking area. | | Dust Protector | Dust and dirt entering through the lens mount of a digital camera, can create serious defects in image quality. If dust and dirt adhere to the image sensor and are not removed, it will degrade the image quality. In order to prevent dust entering and adhering to image sensor, the body mount of the SD9 is equipped with an integral dust protector. The dust protector of the camera prevents dust from entering and adhering to the image sensor. Even if dust adheres to the dust protector it will not have an influence on image quality, because the dust protector is located away from the image sensor. | | Easy To Use Controls | Each button of the Sigma SD9 is ergonomically arranged to provide a functional and easy-to-use setting. By means of the 4-Way Controller on the back of the body, menu settings and camera settings can be adjusted very quickly. By using the Zoom-in View mode, the details of the image can be selected magnified by moving the cursor and choosing the location with the 4-Way Controller. The command dial can quickly select the resolution settings, and the ISO sensitivity setting. It is also possible to make program shift in the Program AE Mode. | | 1.8" type TFT Monitor | The Sigma SD9 is equipped with a large 1.8" TFT-LCD monitor, which displays images, menus and histogram. The coverage area of the LCD monitor is 100%, similar to that seen from the viewfinder and thanks to the LCD-monitor, the composition can also be seen easily. | | By operation of +/- Controller, three types of screen display can be chosen; thumbnail display (9 images simultaneous display), Single-Image display, and a Zoom-in display (the area to magnify can be freely chosen by the 4-Way Controller). By pressing the INFO button, detailed image information can be displayed on the TFT-LCD monitor, such as shutter speed, aperture value. | | IEEE1394 & USB(1.1) Interface | The Sigma SD9 can transmit the images from camera to computer with high-speed Firewire (IEEE1394) (S400) and widely available USB (1.1) interfaces. | | Image Storage Media; CompactFlash Card. | The SD9 employs CF card as an Image Storage Media. Since the SD9 is compatible with the CompactFlash Type I/II card, use of IBM Microdrive (not included) up to 1GB is also possible. | | The outstanding storage capacity of IBM Microdrive enables photographers to use the camera even more effectively. | | Please Note: Image for illustration only. The SD9 does not come supplied with a lens as standard |
