As mine was under warranty, I sent it in last month for AF re-calibration due to BF with my FA*200mm lens. Nothing more than telling my photo guy what the problem was. No lenses, flashes, nonsense. When it returned, Pentax Canada had fixed the base plate, cleaned the mirror and adjusted the AF system. Using the Photo Me method, I see that the model revision is indeed now 8.1 as redknelb reported. As for usage, the AF seems much better with little or no BF and overall quicker response time.
