Operation
Manual focusing is possible.
• This function works only with lenses equipped
with an electronic manual focusing ring.
Manual focusing is prohibited.
• Manual focusing by setting the Lens' Focus
Mode switch to "M" is possible.
Useful Situations
This option disables the manual focusing
capability of the electronic ring provided
on many USM lenses, eliminating the
possibility of accidentally turning the ring
and shifting the focus after autofocusing is
complete.
