AF just too slow, otherwise top

I have the NEX 6, the already improved AF owns and shows the kit 16-50 that it comes. But good is the 1.8 nix. The lens will almost always only times in the wrong direction, even with lots of light. In low light - and for the 1.8er's there !!! - The AF is almost helpless. What really annoys: The camera is looking already before the AF. Instead of remaining in the area, the preset AF value is completely rejected and asked again all over again sharply at half-pressing the shutter button. If, however, at 16-50 and 55-210 as well. So a nonsense, right?

Manual focus must be practiced, because the ways for turning are far. Considering the competitive price and the great Abbildungdqualität and pulls the disappointing AF off, I'm on good 3 stars. AF's just soooo important. Perhaps it is indeed time a software update. Keep I will, because there is no alternative to such a price and therefore you should not complain too loudly here ....
