Flash coverage & focal length
The larger the focal length figure of the lens on a camera, the further away a
subject can be photographed to take up the full screen; but the area that can be
covered becomes smaller. Conversely, with a smaller focal length figure,
subjects can be photographed with wider coverage. The flash coverage is the
area that the light from the flash at a set intensity or greater can cover evenly,
expressed as an angle. The flash coverage at which you can photograph is
determined by the focal length.
By having flash coverage determined in accordance with focal length, flash
coverage can be expressed as the figure for focal length.
