Sigma Imaging leads the field in the 35mm SLR market and, with the launch of the DP1 in 2007 took control of the professional digital compact market. Featuring a FoveonX3 CMOS image sensor – the same as that used in its SD14 DSLR – it was the first digital compact to capture SLR-quality images. The DP2s, launched in February this year, is the latest update.
