My experience is the same as yours Rob, maybe 1% AF failures, and that's with 5 years experience with AF cameras and two different models - three if I count my wife's Espio. It gets it dead right most of the time, and the few failures are generally in situations where I should have known better - like having two people in frame with a big gap in the middle was always going to fool the camera! Now, if the subject is static with good contrast, the camera should get it right, but if contrast is very low it's beyond the design spec - and it says so in the manual. There will be occasions where a manufacturing fault will cause any system to fail, and that's why the first thing I do with any new camera or lens is to shoot at least a few frames, if not a roll or more, to test it's capabilities under varying conditions. With digital, too, there is really no excuse as you can see the results straight away - isn't that supposed to be one of the big advantages?
