What about Nikon 75o focusing on the small frame lock?

The unlock box is l.

1. Make sure that the focus lock switch is in the unlocked position (not on the L). 2. After half pressing the shutter, use the arrow keys to move the focus to the center position. 3. Set the focus lock switch to the lock position L, which can prevent the focus from moving.
