What do you guys use? I always use manual focus. I don't know why, but I always do. I like the challenge of having to focus quick and pay close attention to what I'm shooting. Sure, I mess up shots, but it's fun to me, to have that extra challenge. And you don't always know what your shots are gonna look like till they are uploaded onto the computer, fun stuff! I did sports shooting this weekend at 300mm on a 70-300mm lens, that was a nice challenge right there. But what do you all do, manual or auto focus the majority of the time?
