This is a manual lens, so some of these questions are not relevant. However, for the price this is a very good manual focus lens for my Fuji X-T2. The bokeh is good and there are very few anomalies to notice. Autofocus with manual focus switching to auto would be nice, but for the price of a basic 50mm f1.7 lens it's surprisingly good.
