dpreview har testet Sigma SD9

Hentet fra dpreview`s omtale av Sigmas FoveonX3 kamera :

"Foveon (a previously not-so-well-known technology company) and Sigma (never before produced a digital camera) have had the guts and innovation to come to a very aggressive and critical market with a totally new concept in digital image capture. They have made the first step in what must be seen as a revolution in digital photography."
