10. Autofocus

Even without the USM motor the autofocus mechanism works fairly fast and relatively quietly. The only serious problem we might acounter is the accuracy, which is just avarage. The number of mistakes reached 11%. Fortunately the lens doesn’t show a tendency for back or front focusing.
