Must reach halfway useful quality to it Stopping down to f / 2.8.
The autofocus is so fail as a musket slowly and in low light ratio
The processing and haptics is modest
Who partou f / 1.8 needs or wants has to invest a few hundred euros more and buy either a new f / 1.8er zoom or Sigma type lens.
For the rest there is very good f / 2.8er zooms are sharp even at maximum aperture, make better and are more flexible
