Don't really care if a camera has 45 or 19 AF points. For slow moving or static objects, I almost always use the center AF point, half press the shutter and recompose, or I move the AF point manually.
(I have heard some people argue that recomposing can actually cause a miss-focus due the recompose, I have not noticed that, maybe because I don't have any 1.2 or 1.4 lenses, but for me recompose works every time)
When I shoot our birds, I just don't trust AF, I know where they will be and prefocus on the ground at a distance I know the bird will be at, I turn off AF, and then point the camera to the sky, I know the width of my DoF (I'll be using at least f/5.6 or f/8.0), and I'll burst shoot and I'll get several shots perfectly in focus.
For all the commercials about cameras being able to focus on fast moving subjects, I still don't trust it and don't use it. It's not fast enough and not precise enough, if there's a cloud or tree or anything else in the frame it will miss focus, the camera has no idea that I want to focus on the bird, especially not when it doesn't take up much room in the frame, it will focus on the sky, or cloud, or tree, etc. People say that you can use AF tracking by marking a target with the AF point, I don't know what birds people shoot that allows them to use tracking, but I don't find the time to do this, you can barely see the AF markings on most Canon cameras I tried, let alone do it while looking at a bright sky.
Maybe it's because I'm used to rebel cameras, but the chance that I nail a shot on a fast moving subject by relying on the AF is much smaller than prefocus and creating a large enough DoF. Maybe it works for birds flying high in the sky, but for a fast flying bird a few meters above you, it does not work for me, only prefocus works.
I know people shooting cyclists use this prefocus on the ground trick too. It's the only thing that I trust.
