DOF?DP2m lens peaked at f=5,6, q lense will be the about same, so why shoot it at f=11?
Update your firmware and go to the latest version of SPP.So I now have had the Quattro for a few days. I remain astounded at the sharpness and resolution of the camera. Color has been more of a problem than my initial shots led me to believe. I have not used Sigma software before, so I expect more skill on my part would be helpful. The crops below from a 645D using a 67 55mm at f/11 and the Quattro, also at f/11, indicate a more serious problem of color bleed (I believe that's the correct term). The marigold is red and yellow as it appears in the 645D shot. Is this a problem addressable in software?

I wouldn't assume that. Check the firmware.Thanks for the suggestions. I'm using 6.0.5 and I just received the camera from Sigma 5 days ago, so I assume it's the latest firmware. Using the neutral (vs. standard) setting restored some of the yellows, but not much. It's an amazing sensor, but I am having problems with the color; I'll take Darr's advice and try a Merrill before considering the Quattro.
Darr,
I see you love the Merrills, but you can still post in the MF forum sometimes too.

PS foveon, f/11 to minimize focus errors; I'm not testing the lens, I can see it's fabulous.
Honestly Tom, I have not shot MF in a couple of months. Last week I packed-up some gear including the ALPA kit to head out for a shoot and then the weather turned bad quickly. Unfortunately, Florida is like this in the summer and what I wanted to shoot with the ALPA and Merrills (comparison testing), I could not, so I continue on without any MF results, but I feel no disappointment. The smaller size of the Merrills are making my photographic journeys much easier these days and I find this to be more satisfying because I am getting more work done. Recently I acquired a SD1 Merrill for studio macro work and if I can get it to do what I need it to do, I may be heading out of MF. IMO, the Sigma 70mm macro lens is not as precise as the SK 120 M lens, but for fine art work, it has been showing great promise in my testing. My photography started to take a new direction about 18 months ago. The Merrills were tested to be part of the new direction and they have satisfied me so far and have brought up my productivity level.Darr,

True enough, but in some ways easier when big developments in equipment were years apart, e.g. a new film.................
It truly is a great time to be in photography with all the new technology.

Even less wrong w a $500 camera that can do the same.Perhaps Digiloyd should read this review. Remind me again why some people pay to read that guy's site?
The views expressed in this review by Steve Huff are much closer to my own. I have spent long enough now with the DP2Q to validate Huff's image quality findings with a few caveats mentioned earlier in this thread. There is not much wrong with a $1,000 camera that produces almost flawless medium format like prints at sizes larger than my Epson 7900 can achieve.
I did. In a print, the DP2Q is closer to around something like 35-38mp with a carefully uprezzed shot. A subjective view but based on very large prints even bigger than that.I remember at the beginning of the discussion dedicated to Merrill, he wrote that the DP2 Merrill had a similar definition to a 28 megapixel, more or less depending on the subjects photographed.
