In taking advantage of what this body will do I need to tweak it a bit for better autofocus performance in photographing baseball and upcoming football. Any suggestions as to what to do in the menus to make sure of the greatest number of in focus photos. Don't generally photograph in long bursts but short ones of 2-4 shots to shoot at and through peak action so I get it and a follow on or two of reaction. Only long bursts are things like a big play at home plate, steal and slide series or errors in baseball and running or passing plays coming into the camera in football. Most others are short. AF improvement is increments, not one of not finding AF at all. Anything to increase success is helpful. Love the camera. Recently got two and replaced 40D's I was using. A night and day difference. Much more than the spec sheets would suggest. The photos do look better all the way around and the cameras are a joy to use. The frames per second isn't much quicker than the 40D series on paper but in real world use it is a lot nicer. A lot quieter in use as well and inspires the kind of confidence the EOS 1 series did with film bodies.
