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 o󰀨 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.

lens that cover a large area, to avoid signicant delay from focus search drive
if the lens becomes greatly out of focus.

those that you will use.
