Since 2007 Sigma has developed five DSLR cameras, including the SD9, SD10 and SD14,
SD1 and SD1 Merrill. In 2008, Sigma also added a high end Compact Digital Camera, known as the DP1 which employs the same big image sensor that's installed in Sigma’s DSLR cameras. Sigma has established a dedicated base from a wide array of photographers, of amateur and Pro. Photographers that expressed a wish to include the "TRUE" image processing engine, which is employed in the Sigma DP1, into a DSLR camera. To meet this request, the SD15, featuring a direct image high resolution sensor, has been built around the just released "TRUE II" image sensor processor engine. The new combination provides superior image quality along with quicker processing speed, procedures and performance.
Every Sigma Camera, including SLR and DSLR camera employs the Sigma SA mount, which is mechanically
analogous to the
Pentax K mount plus it's an electrical reworked
copy of the
Canon EF lens mount lens
Sigma lens and Sigma lenses are also made by Sigma as well as the
Sigma SD9 and the Sigma SD10 cameras.
