I bought this lens from my hands, it was brought from Korea. The condition is excellent and there were no autofocus misses, but periodically, it is not clear under what conditions, the motor refused to turn the focus, either in manual or in automatic mode. There was a clicking sound. The problem disappeared by itself, and could appear after a long time just as unexpectedly. It seems to me that the problem was in my battery, and the motor was not getting enough current: during these problems, the battery began to flash red when it showed three sticks of charge a minute ago.
