Hi to all,
so far i see three problems with the DP2m:
1. Banding,
it occurs sometimes in the shadows in out of focus areas mainly starting at iso 200. This is not a big problem. SPP noise reduction takes care of it. This is why SPP has the NR sliders as a standard in the middle position. If there is no banding visible you ca slide them to the left at low iso.
The other possibility is to use NIK Define plugin in LR. Slide NR in SPP way to the left and exp. TIFF 16 to LR. Define has a debanding function: just use these and apply no other NR.
2. Magenta Cyan color blotches,
i find them mostly at ISO 200 and up in shadow areas in mid grey or more whitish areas. Not easy to deal with.
What i do is in LR play with the color sliders: Pic the tone with the pipette and desaturate, change luminance or color. This has to be done carefully,depending the photo, so you dont change other color areas. You can use the brush in LR with a mask and change saturation only locally.
Only a very few of my pics where affected.
3. Cyan greenish cast in the corners (not blotches!)
i made a shot with a WB diffusor in front of the lens:

Reminds me on the Leica M8,9
Convert it to DNG, and used the new "corner fix" plugin from Adobe:
This is the pic before corner fix:

you can clearly see the cyan shift in the corners.
This is after the pug in:

Looks (little) better, more eaven. i Think with more time on could make this process much better.
In general, the best thing to avoid problems is to expose to the shadows +0.3 -+0.7 and to use SPP with care.
