Wow. I hope Sigma will be back in business with these new DP models. Really interesting ones, especially the DP3 Quattro with a 75mm equivalent lens. If the Quattros are faster and have better battery life than the DP Merrill serie then I would be highly interested. Image quality will be a stunning one. I know because I have had DPM 2 with a 45mm equivalent lens. The biggest irritating thing with DPM cameras, and I suppose also with the Quattros, will be the fact that you have to use Sigma’s own RAW processing software, Sigma Photo Pro. That is a very cumbersome and slow programme and I really hope Sigma will enhance its usability in conjunction with the release of the new camera serie. Foveon is a fantastic sensor but unfortunately only Photo Pro will read the RAW files it produces.
