Lenses That May Block the Built-in Flash and AF-Assist Illuminator
The lenses listed in this section may block the built-in flash or AF-assist illuminator under some conditions.
The AF-assist illuminator has a range of about 1.0–3.0 m (3 ft 4 in.–9 ft 10 in.); when using the illuminator, use a lens with a focal length of 16–300 mm. Some lenses may block the illuminator at certain focus distances.
- Remove lens hoods when using the illuminator.
The following lenses interfere with AF-assist illumination:
Lenses that prevent the use of AF-assist illumination for autofocus NIKKOR Z 14–30mm f/4 S Lenses that limit the range at which AF-assist illumination can be used for autofocus NIKKOR Z 24–70mm f/2.8 S AF-assist illumination cannot be used for autofocus at distances under 2.5 m (8 ft 3 in.)
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
Lenses that block the subject’s view of the red-eye reduction lamp may interfere with red-eye reduction.
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.
