Nikon D800, D800E AAperture, Sensitivity, and Flash Range

AAperture, Sensitivity, and Flash Range

The range of the built-in flash 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 0in.–19ft		8in.
2.8	4		5.6	8	11	16	22	0.6–4.2	2ft 0in.–13ft		9in.
4	5.6		8	11	16	22	32	0.6–3.0	2ft 0in.–	9ft 10in.
5.6	8		11	16	22	32	—	0.6–2.1	2ft 0in.–	6ft 11in.
8	11		16	22	32	—	—	0.6–1.5	2ft 0in.– 4ft 11in.
11	16		22	32	—	—	—	0.6–1.1	2ft 0in.– 3ft		7in.
16	22		32	—	—	—	—	0.6–0.8	2ft 0in.– 2ft		7in.

The built-in flash has a minimum range of 0.6 m (2 ft).

In exposure mode e, 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.
