Hi, Just thought I'd send another quick update on the 645DF kit, this time with the 150D that I recently picked up from Jack. So far so very good. Delighted, frankly. As an example, today I took the rig to a whitewater kayak course we have here in town. While it's not exactly like basketball for action, it's still a moving subject with lots of things to challenge and fool an autofocus mechanism. The DF performed extremely well, frankly, MUCH better than I thought it would, and the 150D was just terrific (I think the word I constantly use in describing the 150 is "clarity." It's just a real superb lens). And the camera, I simply can't believe how much more responsive this system is compared to my Contax. In my experience it's way more accurate, with farless hunting. The hunting/searching isn't completely gone, mind you, but it's a helluva lot better than my Contax ever was. I'm developing real trust in complete this kit and that's really good. Ray
