Re: Is RF 28-70 F2.0 suitable for fast moving objects? (AF speed)

How fast are we talking? And how close? I had this lens for a weekend on evaluation loan and used it for a Tennessee Walking Horse show. Not a very erratic subject, but it performed fantastically at any rate. I think tracking quick and erratic subjects can be more demanding with a wide angle than a telephoto (all else being equal), because the size and placement of a nearby subject can change more dramatically within the frame. (Imagine tracking a racecar off in the distance, compared to one as it whizzes by you a few feet away.)
