Instruction manual

Image-Size Lock may not be able to accurately track high-speed
subjects. If your subject is moving too fast, the image size may not remain
constant but IMAGE LOCK will continue to be displayed in the viewfinder
screen.
If you want to use continuous film advance, use low-speed mode.
In the following situations, IMAGE LOCK will flash in the viewfinder screen
when you press the lens function button and Image-size Lock will not
function:
If your subject is too small and/or too far away for the camera to lock on
to it.
If the camera cannot focus on your subject (see Special Focusing
Situations on p.43.)
If the lens is initially set to a focal length shorter than 50mm.
