Recently, Sigma has launched two cameras in its digital camera line up. One is DP2, which is the next version of the DP1 and second one is SD15 the upgraded of SD14. Both the cameras has image sensor that are designed with Foveon X3®. After getting huge supports from the users they have improved and brought the upgraded version.
Sigma claims that their newly introduced DP2 has 20.7mm x 13.8mm image sensor that is seven-twelve time larger than the ordinary compact digital cameras. DP2 has 24.2mm lens with F2.8 big aperture, by using it you can get extra facilities in low light but in DP1 it was just 16.6mm F4 lens. Another important improvement is in AF moods. DP2 can focus in 9 points where as DP1 was just single or more at a time.
