I want to upgrade from a 250mm lens to a 300 or 400mm lens for my EOS Rebel T3i. I know that some of the canon lenses are incompatible but my technical skills are lacking so I don't know the best lenses for my camera. Suggestions?
Thanks for the info. Do you know the difference between theCanon EF 100-400mm f/4.5-5.6L IS II USM Lensand the Canon EF 100-400mm f/4.5-5.6L IS USM Lens There seems to be a $1000 difference between the IS and the IS II
