I've been using them for about 2 years now. I can say with full responsibility - the lens is super! Focuses quickly, keeps the face in focus perfectly. Both for large portraits and for half-length, full-length ones. Backlight holds perfectly. Yes, there is a minus with its weight and size, I donโt always take it with me on long trips on vacation. But I have more zooms. In general - I recommend!
