Focus will remain locked
between shots as long as the
shutter-release button is kept
pressed halfway, allowing several photographs in succession
to be taken at the same focus setting. Focus will also remain
locked between shots while the AE-UAF-L button is pressed.
Do not change the distance between the camera and the
subject while focus lock is in effect. If the subject moves, focus
again at the new distance.
