Warning, this is quite the newb question. My Canon EOS 40D has 9 AF points. In the default mode, it basically somehow decides where to focus.. so it chooses one or more AF points and then tries to achieve focus using those points. My question is, how could I ever shoot a spur-of-the-moment photo.. take off the lens cover, turn on the camera, and shoot? I never know which of the 9 points the camera is going to use. I feel like any time I want to get the right shot, I need to manually set the AF point, and then shoot. How do others deal with this? Do you skip AF altogether and use MF instead? I have trouble using MF through the viewfinder, I don't think my eyes are good enough, but the Live View feature rocks (when I'm on a tripod) and if it's a still object I'm shooting, it lets me achieve perfect focus.
