WOw, thanks for sharing those links! It answered the two questions uppermost in my mind. DxOMark results had the 5dmk3 much inferior to the Nikon D800 and I was very disheartened until I saw these 'real life' tests! 5dmk3 is the new king of low light! Just goes to show, you have to take any test with a pinch of salt. Once again THANK YOU. I am now saving money for the 5dmk3. (My wife hates you tho)
