It contains a 46 megapixel 23.5×15.7mm APS-C X3 Full-color image sensor. The 46 effective megapixel (4,800×3,200×3 layers) and 44 recording megapixel (4,704×3,136×3 layers) 23.5×15.7mm 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, it 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.
With this sensor, ISO sensitivity can be selected from 100 to 6400. The SD1 captures light effectively and ensures noiseless image processing. The image sensor provides high definition with rich, graduated tones.
The Sigma SD1 will be available for the MSRP of $9,700 through select authorized Sigma dealers.
