Dust seems to get through the ring onto my sensor. I don't shoot in crazy dusty conditions, but my back pocket has horrible velcro that squirts white particles at anything I need to blow off/brush off. It seems that is exactly what is happening. That would be my biggest complaint. I think I'm better at portraits than landscapes so far. Close-ups seem to be the best place for this lens. The autofocus seems to chase where my native lens fails. I wasn't too keen on wildlife/sports/videos to be honest. The autofocus on the eyes works perfectly. In the next few weeks I will buy more devices to get really good contrast comparisons.
