LOL I busted out laughing at the amount of detail in these pictures.
HOLY COW!
When used in an environment where the photographer has time to control the situation eg/ landscape and studio work, the Canon files are just awesome to work with. If I worked in a studio, I doubt i'd shoot Nikon.
However, I think for photography on the go, the Nikon ergonomics kick butt.
When I was living in Seattle, i'd regularly shoot with 5D's and 30D's. They were OK to work with, but when I got home to work on the files, it reminded me why I didn't use my D70 instead, even though it might be easier to work with.
EDIT:
Out of curiosity, how is the 24-105 on the 5DII? is it ok at f/4?
