Nice lens, F1.4-F2 is a bit soft and contains chromatic aberations. F2.8+ is really sharp. F5.6-F7.1 produces excellent resolution. AF is very fast. Smooth bokeh, but sometimes those non-rounded eight aperture blades are a bit visible. Build quality very good. Lens is small and light. Contrast can be enhanced by optional lens hood which I strongly recommend to buy. Cheap third-party one for 49mm screw is enough and helps significantly.
Lens hood not provided - 49mm screw hood needed.
