Z Effective range of the built-in flash
The effective range of the built-in flash varies depending on the ISO sensitivity and aperture settings used.
100 125 160 200
1.4 1.6 1.8 2
2 2.2 2.5 2.8
2.8 3.2 3.5 4
4 4.5 5 5.6
5.6 6.3 7.1 8
8 9 10 11
11 13 14 16
16 18 20 22
The minimum effective range for flash control using the built-in flash is 0.6 meters.
*
In programmed auto, the maximum aperture (minimum f/-number) is limited according to sensitivity (ISO equivalency), as
shown below:
100 125 160
2.8 3 3.2
For each one-step increase in sensitivity (e.g., from 200 to 400), aperture is stopped down by half an f/-stop. 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.
MEMO
i-TTL flash control can adjust for ISO sensitivities between 100 and 1600. It may not be able to adjust flash level appropriately for
ISO sensitivities over 1600.
