I owned the same on Canon 6D where there is only one working focus point. It hit just always and everywhere, in any conditions. After switching to Nikon, I wanted the same one. Bought and disappointed. Within the range of up to 3 meters, it hits more or less, but if you move the frame into the distance, it cannot focus. Moreover, it is even visible in the viewfinder that everything is cloudy, and the dot is highlighted as if hit. As a result, I had to pick five times, so that he would focus. And this is on the D800. At the same time, the native 35 f2 D on the screwdriver hits 10 out of 10 on all AF points.
