Agreed, any fast moving event is a problem with capture speed, jpegs are bad enough - don't even think about using RAW. can auto-focus as well as competitive bodies such as the 20D with USM lenses. I've used Pentax, Nikon & Canon bodies at events, and I'm firmly convinced that the Pentax AF is neither as fast nor as reliable as the competition; if my livelihood depended on my ability to bring home the results I would have switched by now. But to suggest auto-focus is unusable is overstating the case. For me, it's not so much auto focus per se, it's in low light conditions I've found the greatest problems with unacceptable noise levels at 800 ISO speeds and above. The D is now so hopelessly outdated, compared with the latest offerings from Nikon and Canon, that unless a significantly updated model arrives soon, Pentax can kiss an even greater number of it's die hard supporters goodbye. Such is the digital age we live. Max
