Photokina report
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.

The Sigma SD1 incorporates a dual “TRUE (Three-layer Responsive Ultimate Engine) II ” image processing engine which improves the processing speed and overall quality of the final image. The unique image-processing algorithm provides high resolution power and reproduces high definition images with richly graduated tones. The autofocus system features an 11 point twin cross sensor. The shifted twin cross type sensor improves Auto Focus accuracy.

Sigma SD1 body
The Sigma SD1 SLR camera adopts a lightweight yet solid magnesium alloy body designed to withstand rough use and shocks in harsh conditions. Buttons and connections benefit from O-ring sealing connections to prevent dust and water getting inside the camera body. The Sigma SD1 camera features a 3.0 inch TFT color monitor. This 460,000 pixel resolution LCD monitor benefits from a wide viewing angle, making it easy to check focusing and composition. Furthermore, the Sigma SD1 adopts the Type I CF Card. The Sigma SD1 camera is compatible with the UDMA enabling fast processing of large amounts of data.

Sigma SD1 lenses
The new Sigma SD1 SLR camera can be used with over 40 Sigma lenses such as ultra-wide, ultra-telephoto, macro and fisheyes which adopt the latest technology such as the FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, SLD glass, Aspherical lenses, Sigma’s own unique Optical Stabilizer function, Hyper Sonic Motor and Sigma’s Super Multi Layer Coating. The Sigma SD1 digital camera meet the various and demanding requirements of all types of photographers.
