DP3 Quattro Digital Camera
Versatile Compact Digital Camera
The Sigma dp3 Quattro Digital Camera combines the 29 MP Foveon X3 Direct Image Sensor with the TRUE III image processing engine to create high quality images with an equivalent resolution of 39 megapixels. Layers of pixels capture the colour data of the red, green, and blue spectra vertically, requiring no interpolation, for a sharper image with better colour gradations.
With this technology is a 50mm lens producing a 35mm equivalent focal length of 75mm; making it useful for portraits, weddings, concerts, or any situation where a medium telephoto can be applied. It has a maximum aperture of f/2.8, useful in low light and for providing separation of a subject from its background. Incorporating a Special Low Dispersion (SLD) glass element and a glass mold aspherical lens, optical aberrations are minimized. For composing and reviewing images, a 3.0" 920k-dot TFT LCD display is available on the back of the camera.
For low light shooting, the camera has an ISO sensitivity range of 100-6400 in 1/3 steps and it has P/S/A/M shooting modes for full control over your exposure. RAW image capture at a max resolution of 5424 x 3616 is also available, and contrast-detect autofocus or a manual focusing ring is available.
