To provide a flash apparatus and a camera provided with the same, which carry out more appropriate adjustment of a light distribution field angle.

The electronic flash apparatus (10) determines the light distribution field angle according to a focal length of a photographic lens (40) and a photographic range on an imaging surface. The electronic flash apparatus (10) includes a plurality of light distribution field angles corresponding to one combination of the one focal length and the one photographic range, and one light distribution field angle is selectable from the plurality of light distribution field angles.
