C.Fn II-4: Lens drive when AF impossible
You can specify lens operation in cases when the camera cannot autofocus
on a subject.
z
0: Continue focus search
If focus cannot be achieved with autofocus, the lens is driven to search
for the precise focus.
z
1: Stop focus search
If autofocus starts and the focus is far off or if focus cannot be achieved,
the lens drive will not be performed. This prevents the lens from
becoming grossly out of focus due to the focus search drive.
o
[1: Stop focus search] is recommended for super telephoto lenses or other
lens that cover a large area, to avoid signicant delay from focus search drive
if the lens becomes greatly out of focus.

those that you will use.
