This item is displayed only with lenses that support it. Selecting
Enable allows the lens focus ring to be used for manual focus
when the camera is in autofocus mode; this is known as
“autofocus with manual override” (M/A). After pressing the
shutter-release button halfway to focus, keep the button
pressed halfway and adjust focus using the focus ring. To
refocus using autofocus, lift your finger from the shutter-release
button and then press it halfway again. To prevent the lens focus
ring being used for manual focus when the camera is in
autofocus mode, select Disable.
