That is one thing I have always loved about Sigma cameras - the ability to print large prints and to do the file justice.
As for the DP2Q I might have to reassess the camera, I still think the camera is overpriced at £899 when I think SPP isn't yet making the most of the files but there seems to more and more people getting some great work out of the camera. I was hoping for a faster camera, with better high ISO capabilities whilst still keeping the distant details intact like the Merrill, sadly I think some of those details are lost in some instances but I think I might just have to get used to the fact that the Quattro and the Merrill are just different beasts. There is some definite improvement in the quality of the images coming out of the DP2Q user base as more and more people are getting acquainted with the camera.

It is a great camera, I was able to make it do strange things to the image like showing the highlight pixels, and highlight pixels giving shot bands of bright colors when using overexposure correction but I feel these are things that will be fixed in future versions of spp.
The IQ is amazing, I don't have a dp2m to compare it with but I do have a dp3m and I agree they are both different.
The Merrils have more film like grain where as the Quattro has a sort of digital grid texture that is prone to adding little vertical spikes (again something that can be fixed with updates I think).
The Merril has more microcontrast and seems to res
olve finer textures in the distance (especially in greens) but the Quattro has more resolution.
Overall they both felt very similar to use, I liked the body of the dp3m more especially the lens focus ring and the fact I can fit my dp3m and my gf1 with 20mm into a small bag that the dp2q won't even go into.
The Quattro has a much better screen though and the color banding in low light that the dp3m shows when framing a shot is gone, the camera is nice to hold and the metal control dials just feel awesome but I hate the plastic focus ring on the lens as the grooved part is very small and recessed so you really grip smooth plastic.
I have quite a few images taken with it, including a portrait of my wife (when she had no make up on) and even she liked it, if I had shot that with the merril id have got a slap in the jaw (due to how it renders

)
I was thinking of writing a little article about my experience with it so far full of images.
This particular image was shot on location with strobes using the cameras leaf shutter to sync flash at 1/800
