So I have been playing with a friends 5d mkii the last couple of days, I am quite impressed with the photo quality upgrade from 40d. The 1.6 crop factor not as bad as I thought, but.... Where in lacks is the snappy focus of the 40d, it takes a bit of time to get focus and the 4ish frames per second was more noticeable than I thought. I think it would make a great second camera with a 7d, or I think I am just going to wait for the 5d mkiii to go on sale in Canada.
