Tim, you're asking very difficult question. Here are some considerations that come to my mind. Could be some of them are incorrect, so please read what I am going to write with critical mind. 1. K10D has very fast AF. I think that it is *way* faster than *istD. I have observed that many times K10D would report that *more than one* AF sensor is in focus (red light), while *istD only reports one sensor. This I think is significant. 2. I don't have 50-200 but I had 70-210 and now have 80-200/4.7-5.6. I couldn't try 70-210 with K10D, 'cause the lens is broken, but 80-200 focuses good and fast. However, at least several times in indoors light the AF hunted. 3. I generally tend to believe that the less the throw from closest focus to infinity the more rapid is AF process. It simply takes less time to rotate the lens. Older tele zooms that I own have rather big focus throw. 4. I've been shooting game of basketball few times with *istD and FA 50/1.7. It were my co-workers playing so that I could physically come very close to them. I've set my *istD to continuous AF and I don't remember missing even a single shot due to AF problems. These are just considerations that popped in my mind. I dare not make any conclusions from these. So, it will have to be you, Tim ;-). HTH.
