Custom Function Settings C.Fn II-4: Lens drive when AF impossible You can specify lens operation in cases when the camera cannot autofocus on a subject. zz 0: Continue focus search If focus cannot be achieved with autofocus, the lens is driven to search for the precise focus. zz 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. oo[1: Stop focus search] is recommended for super telephoto lenses or other lens that cover a large area, to avoid significant delay from focus search drive if the lens becomes greatly out of focus. C.Fn II-5: Limit AF methods You can limit the AF methods available to those that you will use. For details on AF methods, see =188- =190. Add a checkmark [X] to the AF methods to make available. Select [OK] to register the setting. ooThe [X] mark cannot be removed from [1-point AF]. 533
