Notes on Optional Flash Units Be sure also to consult documentation for the optional flash unit before use. • If the unit supports CLS, refer to the section on CLS-compatible digital SLR cameras. This camera is not included in the "digital SLR" category in the documentation for the SB-80DX, SB-28DX, and SB-50DX. • If the flash-ready indicator (c) flashes for about three seconds after a photograph is taken in i-TTL or non-TTL auto mode, the flash has fired at full power and the photograph may be underexposed (CLScompatible flash units only). • i-TTL flash control can be used at ISO sensitivities between 64 and 12800 equivalent. • At ISO sensitivities over 12800, the desired results may not be achieved at some ranges or aperture settings. • In mode P, the maximum aperture (minimum f-number) is limited according to ISO sensitivity, as shown below: Maximum aperture (f-number) at ISO equivalent of: 100 200 400 800 1600 3200 6400 12800 4 5 5.6 7.1 8 10 11 13 * 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.
