|  The new Sigma SD14, powered by the 14 Megapixels Foveon X3 direct-image-sensor, can reproduce high definition images rich in gradation and impressive three-dimensional detail. The Sigma SD14 Digital SLR camera features four JPEG recording modes, large and bright pentaprism viewfinder with 98% coverage, a built-in flash with a Guide Number of 11, 5-point AF system, a large 2.5-inch 150,000 pixel resolution LCD monitor as well as high resolution and user friendly design. The durable shutter mechanism has over 100,000 cycle life and is ideal for digital photography.
The Sigma SD14 incorporates both RAW and JPEG image recording formats enabling photographers to capture the highest possible picture definition and small file sizes. JPEG recording, also built in to the Sigma SD14, can be used for the following printing sizes; Super High (14.15 million pixels: 4608 × 3072 pixels) can be used for A3 (297 x 420mm/11.6" x 16.5") or larger prints. High (4.64 million pixels: 2640 × 1760 pixels) for A4 size (210 x 297mm / 8.2" x 11.6") printing. Medium (2.1 million pixels: 1776 × 1184 pixels) can be used for regular size printing. Low (1.03 million pixels: 1296 × 864 pixels) can be used for web-page and e-mail transmission. There is a choice of three JPEG quality settings: Fine, Normal and Basic.
The Foveon X3 direct image sensor featured in the Sigma SD14 digital SLR can capture all primary RGB colors at each and every pixels arranged in three layers, insuring the capture of full and complete color. 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, it efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Until now, all other image sensors have featured a just single layer of pixels and each pixel captures only one color of light, which has been filtered through a single color filter. Since mosaic-based conventional image sensors capture only one-third of the color, complicated computation is required to interpolate the color they miss. Interpolation leads to color errors, color artefacts and a loss of image detail. Low pass filters must then be used to reduce color artefacts. The use of low pass filters adversely affects sharpness and resolution of the final image captured.
The SD14 comes complete with SIGMA Photo Pro 3.0 software, a RAW image developer that converts all RAW data quickly and easily. Adjustments can be made in three separate modes. The X3F Mode stores the original settings of the image at the point of capture. In the Auto Adjustment Mode, the software analyses and automatically makes adjustments to the RAW data. The Custom Mode allows the photographer to make individual adjustments (exposure, contrast, shadow, highlight, saturation, sharpness and fill-light for example). The photographer can make subtle or dramatic changes easily and quickly by simply adjusting the slider controls within the software.
