One other thing that may help.... I have big hands .... XL gloves. The Canon has a smaller grip pattern on their body then the Nikon. The Nikon there for feels better in my hand... but this will depend for you on what size your hands are.
I went to a bunch of stores and some of them said the Nikon is better and other stores said the Cannon is better. Which one should I get and why?
I would agree if your only going to take Macro shoots. Canon has Nikon beat in this area for sure that lens is the bee's knee's of macro lens. Nikon does not make a lens that will do what that lens can 5:1 mag crazy.
