Although I have bought the lens from dealer of my choice, but I wanted to briefly describe my experience with the lens at the 6D. I have thus been carried out confirmations and different family shoots, otherwise it is currently my top Always with my own children. It did not let me in the past 9 months in the lurch, and the photos are super sharp, in my opinion, sometimes almost too hot - but that's another topic. The autofocus works properly and AV recordings of VC is indispensable. I also feel that it is not as loud or too slowly, so there is a strong buy recommendation from me!
