My problem with this "power zoom" is the fact that the lens keep changing zoom without stopping until it reaches the end of the range (either direction) even with very little turn. It is very difficult to get the lens to zoom to the exact focal length and I end up turning the zoom knob back and forth to get the lens to come to the value I want or, most of the time, close but not exactly.
Does anyone know what am I doing wrong here and how I should do it please?
