In general, the positive aspects cover its shortcomings, for its price it is very competitive with native optics. I got an exact copy, it works clearly on my canon 5dm2 and 6d cameras. There are friends who had problems, but dancing with a tambourine with a docking station solved them. I shoot almost everything for them, reporting, staging. My main combo is 35+135 2.0, I rarely wear 85. If you decide to take this particular lens, then get ready for the fact that you will have to suffer setting up front-back with a docking station, and this is not 5 minutes, but when you do it, you will be delighted!
