Hi,
I am now upgrading from basic Point and Shoots, to a DSLR, a Canon Rebel XTI, and I enjoy nature photography, espically raptor photography. My question is, what quality pictures would you get from a 500mm lense like the one in the link below. Are they good, bad-- blurry. Basically could someone give me a basic summary about these big lenses (please dont get too scientific:)
