This option controls how autofocus adjusts to sudden large
changes in the distance to the subject when AF-C (0 91) is selected
during viewfinder photography.
If Shutter/AF-ON is selected, both the
shutter-release button and the B button
can be used to initiate autofocus.
If AF-ON
only is selected, autofocus is only initiated
when the B button is pressed.
