    This is more than I expected. I feel this lense is lighter than my 70-200. Good reach and image quality and bokeh is amazing.

    Perfection, Canon 100-400mm Lens

    This Canon 100-400mm Lens is a pleasure to use & photo results are the proof, rich in color & sharp from the center to the edges. This MK II lens is superior to the original MK I in terms of a much quicker auto focus along with ease of use. Ifyou're reading this review & looking for a high end zoom lens, don't settle for less, this is the one!
