Sigma just announced that they're replacing the DP1 Merrill, DP2 Merrill and DP3 Merrill cameras with the DP1 Quattro, DP2 Quattro and DP3 Quattro cameras.
If you are a regular reader of this Blog, you'll know that I own a Sigma DP2 Merrill and love it despite its shortcomings. The Merrill cameras are the closest thing in the digital world to film, in my opinion.
Externally, Sigma gave the Quattro series a completely new design. I'm not sure if I like it or not. It is wider, thinner and less tall. The lenses are the same, which is good because they're excellent.
Internally, Sigma made some big innovations that improve image quality and performance. First, Sigma claims that the Quattro series has 30% more resolution than the Merrill cameras. This will most certainly move the comparisons from full-frame to medium-format. Sigma also claims that the Quattro cameras are "much faster" than the Merrill cameras and they've "enhanced noise characteristics." If those claims are true, then the shortcomings that have turned people off to Sigma cameras will no longer be a barrier.
Sigma has not announced pricing, but Sigma has a history of ridiculously overpricing their new releases. Maybe they won't this time. We'll see.
I'm really looking forward to these new cameras. Perhaps a DP3 Quattro is in my future....
