Build quality

Very well made and are solid as a rock.
The feel is also very good.


Conclusion

Nice image quality with quite good sharpness even wide open, especially for a zoom.
Some glow and color fringing are also there but nothing too bad.
Stop it down and it looks very nice.
Also renders quite nice with good bokeh etc.

It is maybe not the lightest but is still somewhat small in size.

Overall a surprisingly good lens.
