A Aperture, Sensitivity, and Flash Range
Flash range varies with sensitivity (ISO equivalency) and aperture.
Aperture at ISO equivalent of Range
100 200 400 800 1600 3200 6400 m ft.
1.4 2 2.8 4 5.6 8 11 0.7–8.5 2ft. 4in.–27ft. 11in.
2 2.8 4 5.6 8 11 16 0.6–6.0 2ft.–19ft. 8in.
2.8 4 5.6 8 11 16 22 0.6–4.2 2ft.–13ft. 9in.
4 5.6 8 11 16 22 32 0.6–3.0 2ft.–9ft. 10in.
5.6 8 11 16 22 32 — 0.6–2.1 2ft.–6ft. 11in.
8 11162232—— 0.6–1.5 2ft.–4ft. 11in.
11 16 22 32 — — — 0.6–1.1 2ft.–3ft. 7in.
16 22 32 — — — — 0.6–0.8 2ft.–2ft. 7in.
The built-in flash has a minimum range of 0.6 m (2 ft.).
In mode P, the maximum aperture (minimum f-number) is limited according to ISO
sensitivity, as shown below:
Maximum aperture at ISO equivalent of:
100 200 400 800 1600 3200 6400
2.8 3.5 4 5 5.6 7.1 8
If the maximum aperture of the lens is smaller than given above, the maximum value for
aperture will be the maximum aperture of the lens.
