The Sigma SD15 is an updated version of Sigma SD14 DSLR produced by the Sigma Corporation of Japan and featuring the improved TRUE II image processing engine, but with the same image sensor as its predecessor. As such, the SD15 features the 14.7MP Foveon X3 sensor. After having showcased the camera in Photokina 2008 and officially introduced during PMA 2010, it finally began shipping on June 2010[2]. It is Sigma's fourth DSLR since the SD9 from 2002. As of November 2011, they are being sold off in Germany complete with lens for EUR 379.-

Differences with the SD14

While the SD15 retains the image sensor from its predecessor, it includes the improved TRUE II image processing engine that was already implemented in the Sigma DP2. Sigma claims that the new engine offers better quality with a faster processing speed while suppressing noise through a newly developed proprietary algorithm[3]. The combination also offers a one-stop higher ISO range compared to the SD14, though the often desaturated rendition of natural green and oversaturation of blue has been retained.

The SD15 also features a larger, higher resolution LCD screen.

The storage medium was changed from a CF card to an SD card.
