Although I have not bought the BG-E11 at Amazon, would like to express briefly to me yet. This battery grip increases the anyway very good feel of the Mark 3 again by a few steps. The camera is with him perfectly in the hand, almost like an EOS 1D ... The vertical photography is greatly facilitated. The handle is processed 1A and is very convenient. He will not budge on the camera wobbles and moves because nix. Since then I have screwed the handle on my Mark 3, me this great camera even more fun. With me he will stay forever tuned! Full marks from me!
