After the Birdfair I am seriously looking at getting a Canon 7D but if I do get one do you recommend a battery grip, and if so which one? Do they make much difference? I notice the screen on the back of my old 40D always seems dimly lit and poor quality, not sharp at all, would a 7D & battery grip impove this? I was looking at someone with a Nikon D700 of something the other day and his screen was so much brighter and bang on sharp, it made mine embarrassing. Will i notice much improvement on my 40D with a 7D with this? :mad :
