But, I have to ask, what is the point of several out-of-focus
images mixed with the in-focus pictures? Why waste the card
space and then have to weed through the slightly out-of-focus
images?
Pay special attention to these two settings. You will need to
decide—based on your style of shooting—whether you want
your camera to refuse to take an out-of-focus image. If you
set a1 and a2 to Focus priority and you try to take an
out-of-focus image, the Shutter-release button will simply not
release the shutter. The green in-focus indicator in the
Viewfinder will have to be on before the shutter will release.
My Recommendation: Personally, I set both a1 and a2 to
Focus priority. I’m not a high-speed shooter, so I don’t need
my camera to take a picture “no matter what” if that includes
a series of out-of-focus images. What good are out-of-focus
images? We’ll discuss this even more in the chapter titled
Chapter 11.

Dynamic AF area lets you choose the number of AF points
used when you put your camera in Dynamic-area AF mode.
First, let’s review Dynamic-area AF; then we’ll discuss how a
larger or smaller number of AF points (9, 21, or 51) might
help us with autofocus (see Figure 4-7). Dynamic-area AF
mode works by allowing you to control a single AF point,
using it to initiate good focus. You can move your selected
