Aperture, Sensitivity, and Flash Range

The range of the built-in flash varies with sensitivity (ISO
equivalency) and aperture.

The built-in flash has a minimum range of 0.6 m (2 ft.).
In programmed auto exposure mode (mode e), the maximum
aperture (minimum f-number) is limited according to ISO
sensitivity, as shown below:
200 400
3.5
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.
