The Built-in Flash
The built-in flash can be used with lenses with focal lengths of
16–300 mm, although in some cases the flash may be unable to
entirely light the subject at some ranges or focal lengths due to
shadows cast by the lens.
• Peripheral illumination may drop at focal lengths under
16 mm.
• The NIKKOR Z 14–30mm f/4 S casts shadows in photos taken
with the built-in flash at all focal lengths. Other lenses that
restrict use of the built-in flash are as follows:
Lens Minimum shadow-free focal length/
minimum shadow-free focus distance
NIKKOR Z DX 16–50mm f/3.5–6.3 VR 16 mm/0.6 m (2 ft)
24–50 mm/No vignetting
NIKKOR Z 24–70mm f/2.8 S 70 mm/1 m (3 ft 4 in.)
NIKKOR Z DX 50–250mm f/4.5–6.3 VR 50 mm/1 m (3 ft 4 in.)
70 mm/0.8 m (2 ft 8 in.)
100–250 mm/No vignetting
D Red-Eye Reduction
Lenses that block the subject’s view of the red-eye reduction lamp may
interfere with red-eye reduction.
A More on the Built-in Flash
• The built-in flash has a minimum range of about 0.6 m (2 ft).
• Remove lens hoods to prevent shadows.
Note: Shadows appear in photographs when the lens blocks the light
from the flash.
