this; one is to assign registered AF points to a
button via [Custom Controls], as discussed on
page 48.
The second method is the [Register/recall
shooting function], again within Custom
Controls. This allows memorizing a number of

forehand stroke with a manually
selected AF point at the upper

switch not only AF point, but potentially the AF
Area as well.
Further refinement in operation is possible
with the <Depth-of-field preview> and the
<Lens AF stop> buttons when set to ([Switch

the choice to [Switch only while pressed] or
[Maintain switching until pressed again],
giving even more control to the photographer.
