I am not sure how your friend gave you proper DNG files from the DP2 Merrill. The only way I know of would be 'second-hand' files in the sense that they would have to be converted to TIFF first, then to DNG. Lots of good data thrown away there and not a good representation of what those files really hold.
Neither do I; I donīt know the person. But thats what I got.
Here's an example of the banding problem. Please click here and check the forehead/nose. I used the medium setting here, and it's still clearly visible. 6s shutter time, but still..
I was taking some pictures today in good light, and had to crank the banding removal slider to the middle again to get rid of banding. At 1/40s shutter and ISO100, this really shouldn't occur..

As far as could read banding occur with this camera when:
1. itīs working for hours and gets really hot.
2. hot weather; gets really hot too (of course).

Maybe I'm picky, but the effect is visible in pretty much every image if banding noise removal is below the middle setting. Single shots, short exposures, outside or indoors etc. Long exposures seem to make the problem worse, and lines can't be eliminated in SPP. It's hard not to pixel peep with this camera

Please check the full size image. There are clear visible vertical lines, which I can't get rid of. I checked on two calibrated monitors here
Here's a 200% crop

I' ll see vaquely what you mean only in the background above the dog's head. What ISO? Very dark there.
I never tryed these kind of "portraits' with not much light with the DP2m.

I see now clearly the lines like this was a print on paper with texture. Vertical lines.
Jede you should share you raw file so we could open it here and see better. Iīve the SPP.

You might want to get your camera checked then, I haven't experienced what you are detailing at all. Do these lines show up in your prints? (I would put money on it that they don't...)
And yes, it is hard not to look at the detail this camera provides at 100%.
