SIGMA Digital SLR Cameras

	Sigma - SD10 Sigma in October of 2003 launched the new Sigma SD10 Digital SLR camera. This high-definition digital SLR camera is powered by Foveon X3® image sensor, which captures all RGB colors at each and every pixel. With the RAW data recording system of the SIGMA SD10, it is possible to obtain high picture definition and compact file size. The lossless compression system of RAW data, eliminates image deterioration, provides superior pictures, without sacrificing original image quality and retains full image capture details. (review coming in January 2004)
	Sigma - SD9 The Sigma SD9 is the original Foveon image sensor supplied digital SLR camera and just as valid today as the day it was launched. The ISO ratings are more modest and a number of other features are not as advanced as on the SD10 but the images are the same and the camera can be had at a significantly lower price. Some camera stores in the US are listing the SD9 body for as little as US$ 700. So if you are looking for a DSLR bargain they are out there to be had.
Compact - Lightweight Sigma zoom lenses designed to suit the characteristics of digital cameras.
	SIGMA - 18-50mm F3.5-5.6 DC Sigma Corporation is pleased to announce the launch of the new 18-50mm F3.5-5.6 DC. This zoom lens was exclusively designed to suit the characteristics of digital SLR cameras. The image circle was designed to match the size of the image sensors of digital SLR cameras, and this produced a compact lens with a maximum diameter of 60mm (2.3 in.), overall length of 67.5mm (2.6 in.) and weight of only 245g (8.6 oz.). It has a variable angle of view of 76.5 degree - 31.7 degree. The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produce high level of optical performance. 18-50mm F3.5-5.6 DC lens has a minimum focusing distance of 25cm (9.8 in.) at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.5.
	SIGMA - 50-200mm F4-5.6 DC Sigma Corporation is pleased to announce the launch of the new 55-200mm F4-5.6 DC. This compact telephoto zoom lens was exclusively designed for use with digital SLR cameras. The image circle was designed to match the size of the image sensors of digital SLR cameras that also allows compact body and lightweight with overall length of 84.6mm (3.3 in.), and weight of only 310g/10.9 oz. It has a filter size of 55mm, maximum diameter of 70mm (2.7 in.). This remarkably compact high performance zoom lens is ideally suited to a wide range of subjects. This lens has a minimum focusing distance of 110cm (43.3 in.) and maximum magnification of 1:4.
	FOVEON X3(R) Direct Image Sensor Foveon X3(R) direct image sensor in the Sigma SD10 digital SLR can capture all RGB colors at each and every pixel. The revolutionary design of Foveon X3® direct image sensor features three layers of pixel sensors Using three silicon-embedded layers of pixel sensors, stacked to take advantage of silicon's ability to absorb red, green, and blue light at different respective depths, the Foveon X3® direct image sensor can thereby directly capture full color and detail at each and every pixel location, without interpolation. Other conventional image sensors feature just single layer of pixel sensors in a tiled mosaic pattern. Each pixel detects only one color of light, which has been filtered through a single red or green or blue color filter. As a result, two thirds of the color information at each pixel is blocked out. To compensate, the missing color is estimated through a complicated process of color interpolation, leading to color errors, color artifacts and loss of image detail. Sigma SD10, powered by Foveon X3® direct image sensor, however, captures all three colors at every pixel location, ensuring the capture of full, complete color. It efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor.
