OK - in full disclosure I was about to write up a post how I was disappointed with some of the noise in the high ISO shots being offered on Canon Europe's website. Then - in order to be fair I figured I should compare the photos to the 5DMKII. Wow - what an improvement! I just downloaded some 6400 full res MKII samples, and the improvement is staggering.
Here is a side by side comparo...
Original 6400 5DMKIII image: http://cpn.canon-europe.com/files/education/technical/inside_canon_eos_5d_mark_iii/16_cinc_big.jpg
Original 6400 5DMKII image: http://www.dcresource.com/reviews/canon/eos_5d_mk2-assets/nightshot6400.jpg
Another 6400 5D2 image in more "normal" light conditions: http://www.stevehuffphotos.com/Steve_Huff_Photos/CANON_5D_MARKII_REVIEW_AND_SAMPLES_2_files/iso6400fullsizewinny.jpg
I'm amazed at the improvement in noise reduction!
