RELEASE
PRIORITY VS. FOCUS PRIORITY (continues ...)
From my own testing with the D2x I find that Focus
Priority almost always gives me well-focused pictures.
When shooting quickly it may skip a series of out-of-focus
ones, but I don’t want those anyway. Focus Priority
will impair your camera’s frame rate, so that it will
not reach the maximum 5 fps or 8 fps. But, I have to ask,
what is the point of 10 out-of-focus images and 5 in-focus
images? Why waste the card space, and then have to weed through
the slightly out-of-focus images?

In
Figure 1 below are pictures of the series of menu screens
used to set Release vs. Focus Priority.
For
AF-C
Mode using Custom
Setting a1:
In
AF-C mode and Custom Setting a1, “FPS rate”
and “FPS rate + AF” are both forms
of Release Priority, with “FPS rate + AF” giving “improved”
autofocus while still allowing the image to be taken no matter
what. For reliably sharp focus in AF-C mode, use Focus Priority.
On this menu, it’s the bottom selection.
Now,
let’s turn our attention to AF-S mode and Custom Setting
a2. We need to verify whether Focus or Release Priority is set.
Examine Figure 2 for the correct sequence of menu items.
For AF-S
Mode using Custom Setting a2:
In
figure 2, your choices are “Focus”
and “Release.” Since the factory
default is Focus Priority, it may already be set to “Focus.”
If not, then select Focus.
Congratulations!
Now your Nikon D2x is set up to take an image ONLY if it can
focus on your subject.
