It was a bit mischievous of me to ask because I know that if there was a solution it would have circulated by now. For a long time I thought I must be the only person to think autofocus was crap for fast/long lenses, photography magazines test autofocus ad nauseam, I only use autofocus for snapshots with small apertures. It isn't good enough on any of the cameras I have tried, Canons D30, 10D, 5D and 1Ds Mk2, nor a Nikon D200 if using a fast prime lens. You never get focus on eyes automatically and on flying birds an in focus wing with soft head is the best to hope for. Using just the centre point, focus lock and re-framing works a bit like an M leica though!
