I am not very keen on tests these days. When comes to IQ, all modern cameras are very good, the difference is minimal, pixel peeping and testing are pointless and mostly academic IMO.

Then I saw quite a few people are interested in 6D and D600's low light performance and thought I would test these cameras at ISO6400 and share them here. Didn't try them at higher ISO because if you were going beyond ISO6400 you were living dangerously, no camera is that good. Anyways these are my findings for those who love looking at 100% crops.

All RAW. Converted to JPEG in LR4. Color NR set to 25, Luminance NR and sharpening 0. No other changes in LR. Pictures were then opened in CS5 to reduce D600 files to the same size as 6D.





These were taken in late afternoon, light coming through one window. Used 24-70 V2 for Canon and 24-85 VR kit lens for Nikon. Then I waited for sun to go down, turned the light on and changed Nikon lens to 14-24/2.8.



Life is short.

Travel with passion.

First and last pairs show clear diffedfnce in focal planes. On the last pair, the curtain behind is more blurred on the 6D  than on the D600, and the lettering on the back of the bottle is visible on the D600 and not on the 6D.

I think the D600 was backfocusing a bit in all these samples. Did you check AF finetuning?

Re noise, well, 6D seems a bit better, but then you may be just seeing the effect of the RAW converter and settings. Other files I checked showed D600 with slightly more noise and detail, 6D less noise and a bit less detail.
