Hi all thinking of getting a canon 7d need advise on the pros and cons. Can not get sharp pics of wild life (birds etc) the lens I use for wild life and sport is a sigma apo 150-500mm f5-6.3 DG OS HSM and a canon 350d I know its a big jump from a 350d to a 7d as I can get the 7d for £653.50 any advise would be helpful
thanks
steve
