infrared Focusing Index 1}
The red dot located Just beside the focusing index
on most lenses is the infrared focusing index. When
shooting with black-and-white infrared film, it is
necessary to refocus the lens to compensate for the
fact that infrared rays focus at a point slightly in front
of visible light. To use the index, focus on your subject
through the viewfinder, then look at the lens and take
note of the focused distance. Finally, reset the focus­
ing ring so that the desired distance is aligned with
the red dot.

Viewfinder Ready*Light
When the Nikon FG is used together with N kon flash
units such as the SB-18, SB-16B, SB-15, etc., a view­

without having to take your eye off the viewfinder.
Depending on which Nikon flash unit is attached, the
same LED blinks to warn of insufficient flash output,
incorrect setting of the flash unit or incorrect setting
of the FG, For more detailed information, refer to the
flash unit's instruction manual.
Note: W hen the camera's meter switch is off. the ready-light
will not light up except at the M90 or В setting.
