• Selected focus area can be locked by rotating the focus area selector lock
lever to lock position.
AF-Assist Illuminator
•When the subject is dark and the shutter release button is pressed
lightly, the camera's AF-Assist Illuminator automatically turns on and
enables autofocus operation in a dark environment.
• AF-Assist Illuminator automatically turns on in the following situations:
Focus mode is Single Servo AF, AF Nikkor lens is used, subject is dark and
centre focus area is selected or Dynamic AF Mode with Closest Subject Priority
is activated.
• Focal length of the usable AF Nikkor lens is 24-200mm and the distance range
of the AF-Assist Illuminator is approx. 0.5-3m.
NOTE: Continuous use of the AF-Assist Illuminator_____________
When the AF-Assist Illuminator is used continuously, illumination is limited
temporarily to protect the firing tube. The illumination restarts after a few
moments. Also, when the AF-Assist Illuminator is used repeatedly in a short
period of time, be careful not to touch the AF-Assist Illuminator lamp because
it may have become hot.
Optional Speedlight and AF-Assist Illuminator_______________
When an optional Speedlight is attached and the condition for the AF-Assist
Illumination is met, the AF-Assist Illuminator of the optional Speedlight SB-28/
28DX, SB-27, SB-26, SB-25 and SB-24 automatically turns on. With other
optional Speedlights, camera's Illuminator turns on.
• Autofocus using the camera's AF-Assist Illuminator cannot be performed due
to vignetting with following lenses at shooting distance within 1m:
AF Micro 200mm f/4 IF-ED, AF-S 17-35mm f/2.8 IF-ED (24mm or longer
focal length), AF 20-35mm f/2.8 IF, AF 24-120mm f/3.5-5.6 IF, AF-S 28-
70mm f/2.8 IF-ED, AF 35-70mm f/2.8, AF Micro 70-180mm f/4.5-5.6 ED
• Autofocus using the camera's AF-Assist Illuminator cannot be performed due
to vignetting with AF-S 80-200mm f/2.8 IF-ED, AF 80-200mm f/2.8 ED and AF
VR 80-400mm f/4.5-5.6 ED.
Focus Lock
• Focus lock is useful in autofocus shooting when you want to capture a
subject that's framed outside of the F80/F80D/F80S's five focus areas,
and in situations where autofocus may not work as expected (page 46).
Focus lock is operated differently in Single Servo AF or Continuous
Servo AF.
