Booked in advance must be said that I use the Obejtkiv as a pure sports lens. I use it mainly in halls where the light for most lenses is too weak to erziehlen useful results. After a long search for the right lens then opted for the Canon EF 85 1.8. In order to do justice to my title, I will explain briefly why ping pong is the best example for indoor sports photography. Table tennis is the fastest ball sport in the world and then you also need very very high shutter speeds the movement to "freeze". This is only possible when the lens very bright and the necessary focal length, since you do not get so close that comes to most buildings on the player or on the plate. The autofocus is very fast, quiet and accurate. The background is nicely blurred. I've already made several thousand pictures with the Objekiv and must say that I am absolutely thrilled and I can not for indoor sports shooting only recommend!
