When the autofocus mode or the in-focus indicator is
unsuitable for focusing
When the autofocus function or the viewfinder's in-
focus indicator [O] cannot be used for focus confirma-
tion for the following reasons, focus on the subject in
the manual focus mode with the aid of the matte field in
the viewfinder as you would with a non-AF SLR camera.
a) The in-focus indicator blinks because the subject is
difficult to autofocus.
b) The maximum aperture of the lens in use is smaller
than 5.6.
с) A bellows 100mm f/"4, Shift 28mm f3.5 (shifted),
or Reflex lens is in use.
d) An old type screw-mount lens fitted with an optional
"Mount Adapter К".
How to focus on the subject
1. Set the focus mode switch to [MF].
2. While looking through the viewfinder, turn the focus-
ing ring to the right or left until the image in the view-
finder is clearest.
