The Sigma SD14 is a digital single-lens reflex camera produced by the Sigma Corporation of Japan. It is fitted with a Sigma SA mount which takes Sigma SA lenses. The camera was announced on August 29, 2006 with a "teaser" advertising campaign and was unveiled at the Photokina trade show in Cologne, Germany on 2006-09-26. After production delays, Sigma announced the official release of the SD14 to be on March 6th, 2007. Sigma has released sample images on their website. Contrary to most consumer Bayer sensor based cameras, the Foveon X3 sensor does without anti-aliasing filters and is not susceptible to color aliasing due to the RGB color stacked pixels. Foveon sensors don't form artifacts like Bayer sensors; sharpening tools can be applied to create high resolution images. Foveon images are easily enlarged without the same artifacts and degradation seen in Bayer sensored images. The circular infrared dust-protector-UV/IR-blocking filter can be easily removed, converting the SD14 into an infrared-sensitive camera. The Sigma SA lens protocol is a clone of the Canon EF protocol which provides a not so obvious but very interesting option that most Canon EF lenses will work seamlessly
