It may be because the Sigma Photo Pro (SPP) converter hasn’t yet been optimised, but the initial RAW/JPG images I’m seeing from the new Sigma DP2 Quattro are somewhat disappointing.
The images are suggesting that image quality has suffered (as compared to the Sigma Merrill) with the re-design of the fabled Foveon sensor. I hope they haven’t indeed messed things up.
This is reminiscent of the whole Leica M240 vs. M9 business.

Interesting…..Is this your own images Peter or seen somewhere else? I have not seen any as yet…but it wouldn’t surprise me at all if they have messed it up!!
On the ‘net. There are images floating around in both RAW and JPG formats taken with both cameras at the same time.
I think the more technology advances the less I am drawn to it…in so many ways. Though it’s not all bad!!
I love the files put out by my DP1 and DP3 Merrills. I’m worried about the Quattro too, simply because there are no longer three layered photosites at every point; the 2 lower layers now have a much lower resolution. Now I may not be a mathematician but surely some sort of interpolation is now required? Some early commenters are saying that the Quattro puts out better colour with better noise handling – but at what cost? I guess we’ll have to wait and see.
Yesterday was my Quattro Day. The three layers camera with a different Foveon sensor layout as before operates smooth and feels elegente in my hands. It is a real photographic tool. Thats all what i need and i am looking for.
I thin I saw those files, the ones with the birds? I thought the same: Average.
