When the distance between the camera and subject is less than approx. 2 m (6.6 ft.),
you can take more natural-looking close-up pictures using the wide-flash adapter.
Be careful when using a long lens that the light from the flash is not obstructed
by the lens barrel.
Vignetting may occur in close-up flash photography due to the illumination
pattern, lens in use, focal length setting, etc. Therefore, make test shots before
shooting an important assignment.
When the SB-900 is attached to the camera and used as the only flash unit,
tilting down the flash head is recommended to ensure sufficient illumination of
the lower portion of the subject in close-up photography.
A bounce-down icon appears when the flash head is tilted down.
