You're talking about the wrong camera. The autofocus issue was one that troubled the 1D Mark III, not the 1Ds Mark III. The 1D version is a sports and action shooter camera capable of shooting 10 fps. The ability of that camera to hold focus on an object that was moving toward or away from the camera is important. Canon fixed the problem some months ago, and I don't think it's an issue any more. That problem did not render the camera a failure. Far from it. As to the 1Ds -- the focus tracking (AI Servo) was never a problem; it was resolved before 1Ds' release. Further, the 1Ds is not geared to sports/action. It shoots at a much lower frame rate, and with it's 21 megapixel sensor, is the choice of many fashion, commercial, and even landscape photographers, who aren't likely to have much use for the AI Servo.
