Samuli, I wish I have half of your PP skill. All your pics have ultimate fidelity.
 everybody always says that and my actual trick is that I don't do PP...
I have "published" all my tricks here FM forum, so feel free to use techniques discussed, few links:
my PhotoMatix settings
my resize and sharpening
(very similar results can be achieved with Lanczos resizing (ImageMagick, Matlab etc.) and then adding PhotoShop USM 250%, 0.2px, unfortunately I have not been able to find similar sharpening method in ImageMagick, even it's supposed to work same way as PS USM)
I wish I would have found Zeiss and Leica earlier and not needed to learn all the PhotoShop stuff I had to learn and use during years of using Canon lenses...

Well, at least Nikon boosted resolution quite a bit up. Tho cant say I like their color accuracy. Red channel starts to have some more green in it, almost like Canon.. Tho when I see yours 5DMK2 shots, I dont worry about that much. Still I dont like Nikon colors too much..
Kinda wonder hows possible when 5DMK2 has 50:50 (almost) red/green in red channel and still has 80 metamerism index. While Nikon D800 has really more red than green, but lower metamerism index..
? I have not studied that deep, to me the colors of D800(E) photos I have seen look very good (better than 5DmkII to my eye), with exception of it's tendency to create "neon greens", which I believe is more function of wrong white balance and bad RAW converters.
For my shooting green and it different shades and tones are extreme important and I have been very pleased 5DmII in those. Only camera I have seen giving better greens was 1DmkIII I used to shoot some years back (it has excellent colors on other channels as well).

Btw. Samuli, do you have color profiled (custom ICC) your 5DMK2 (and some Zeiss lens)? Your photos seem to have sometimes quite a bit better colors than lots of 5DMK2 photos I saw..
No, I haven't created custom profiles since I stopped using Canon lenses. Problem with most ICC creation softwares is that they create profiles with mapping tables, which will cause sometimes coarse transitions/gradients. I have not even used profiles for dcraw.c usage anymore - I think I prefer it as pure as possible. Zeiss lenses with dcraw.c linear 16-bit output and gamma adjustment for displaying gives very pure and natural colors, thou will be VERY time consuming.
Also one big difference between my photos and most other is that I use Apple Aperture, while majority of people use Adobe RAW conversion (Lightroom or PhotoShop). Personally I can't get as good results with Adobe's RAW conversion (haven't thoroughly evaluated newest version yet), even with lots of time wasted adjusting each photo, while with Aperture I don't need to adjust RAW prameters at all (except color temp and cast). Naturally I have also paid lots of attention to environment I work; room used for photo processing has 5000K lights and during daytime I can take reference from window showing my backyard. All devices, except iPad, I work with are color calibrated, even now I'm writing this from sofa with laptop connected to my television, which I have calibrated...
My recipe for good colors is based to few basic things (normal single exposure photos):
- correct exposure at camera (I would estimate I need to adjust exposure in less than 5% photos in Aperture, even then most adjustment are less than 0.3 stop, rarely maybe less than 0,5% needs extreme adjustment like 0.6 stop)
- correct white balance (5DmkII default is to set magenta tint to 4 or 6, I use always ~15 and I fine-tune color temp in Aperture - PS. this can be set up in camera so you don't need to adjust it for every photo)
- correct black level (Aperture default and 80% photos I adjust it to 3.5-5.0)
- don't do any processing to image (>99% of my images won't have anything else except what is mentioned above)

Love the 2/28 Samuli!
Lovely lens, for some reason not very popular, not many photos in this thread. Some more:
Carl Zeiss Distagon T* 2/28 @ f/11, 0.6s, ISO 100 - larger
Carl Zeiss Distagon T* 2/28 @ f/5.6, 1/15s, ISO 100 - larger
Carl Zeiss Distagon T* 2/28 @ f/8, 1/6s, ISO 100 - larger
EDIT: forgot to write EXIF data...fixed
