Photokina news report - Sigma announces the SD1 digital SLR camera, incorporating a 46 megapixel 24×16mm APS-C X3 direct image sensor. The SD1 is Sigma’s flagship digital SLR camera, adopting a lightweight yet solid magnesium alloy for its body and O-ring sealing connections to make a weather-resistant design throughout for use in harsh conditions. The Sigma SD1 DSLR camera incorporates a 24×16mm direct image sensor and dual “TRUE (Three-layer Responsive Ultimate Engine) 2” image processing engines. The combination of the 46 megapixel sensor and dual TRUE II processing engines ensure the high resolution pictures are processed quickly with high definition and a smooth and subtle graduation of colour.

Sigma SD1 - 46 Megapixel camera
The new Sigma SD1 is Sigma’s latest SLR camera which meets high requirements of professional and enthusiast photographers for all types of photography. The 46 megapixel (4800x3200x3 layers) 24x16mm APS-C X3 direct image sensor featured in the Sigma SD1 captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. Using three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon’s ability to absorb red, green and blue light at different respective depths, the Sigma SD1 efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moiré is not generated, the use of a low-pass filter is not required, meaning light and color, generated by the 46 megapixel APS-C X3 direct image sensor is captured with a three-dimensional feel.
