But when you press the shutter release button, the camera may change your focal point to something other than your subject.You just can't get that button down fast enough. I have had shots taken with AF.S and release priority where I had the camera set up, I press the shutter release button, the AF moves the focal point slightly before the shutter is released, and absolutely nothing is in focus. What we are talking about here is what happens to us out in the field. Not some theoretical concept of how the camera should work derived from some manual or how people imagine the camera is supposed to work.
You can learn a lot about how to use you camera, trying to capture hummingbirds. They condense the need to understand a lot of different photographic approaches into one photoshoot. You go through a lot of "Well that didn't work, how about this." And MF using a preset hyperlocal distance is one of the tools you'll find useful from time to time.

Compared to the AF test shots, no MF image is anywhere close to sharpness.
In doors, in indoor light your DOF is going to be so narrow your subject may move out of your DOF before you get the shutter release all the way down. I shot portraits for yeas in MF using a depth scale instead of the split screen focus. If people are sitting still, there's absolutely no excuse for missing focus if your MF lens has a distance scale and DoF guide. Use a tape measure to determine the distance if you have to, but like most things, after a few shoots, you don't need it anymore. You have the distance, (and usually your exposure) just from eyeballing the scene.
