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:

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.
