The Sigma SD1 is a digital SLR camera produced by the Sigma Corporation of Japan. The camera uses a Foveon X3 sensor, which comprises 3 layers of 4800 x 3200 pixels (46 megapixels), giving much higher chromatic resolution than the equivalent Bayer array. It uses a Milbeaut image processor. The Foveon sensor does not use an aliasing filter, thus further improving the resolution.

The SD1 was announced by Sigma at photokina 2010 on September 21, 2010. It was officially put on sale in May 2011 at a RRP of nearly US $10,000. [1]

Sigma SD1 Merrill

In February 2012, the SD1 was relaunched as the SD1 Merrill, honoring the late Richard B. Merrill, inventor of the Foveon sensor. With the relaunch, the price was dramatically cut, to a recommended price of US$3300 and a minimum advertised price of $2299. Sigma gave existing SD1 owners credit toward the company's lenses and accessories equal to the price cut. [2]

The Foveon X3 sensor is a digital camera image sensor designed by Foveon, Inc., and manufactured by Dongbu Electronics. It uses an array of photosites that consist of three vertically stacked photodiodes. Each of the three stacked photodiodes has a different spectral sensitivity, allowing it to respond differently to different wavelengths. The signals from the three photodiodes are then processed as additive color data that are transformed to a standard RGB color space. In the late 1970s, a similar color sensor having three stacked photo detectors at each pixel location, with different spectral responses due to the differential absorption of light by the semiconductor, had been developed and patented by Kodak.

A digital camera back is a device that attaches to the back of a camera in place of the traditional negative film holder and contains an electronic image sensor. This allows cameras that were designed to use film take digital photographs. These camera backs are generally expensive by consumer standards and are primarily built to be attached on medium- and large-format cameras used by professional photographers.

The Sigma SD10 is a digital single-lens reflex camera (DSLR) manufactured by the Sigma Corporation of Japan. It was announced on October 27, 2003, and is an evolution of the previous SD9 model, addressing many of the shortcomings of that camera. The Sigma SD10 cameras are unique in the digital DSLR field in using full-color sensor technology, and in that they only produce raw format images that require post-processing on a computer.

<span class="mw-page-title-main">APS-C</span> Image sensor format

Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm and Ø 31.11 mm field diameter.
