Refer to the flash unit manual for detailed instructions. If the unit 
supports CLS, refer to the section on CLS-compatible digital SLR 
cameras. The D500 is not included in the “digital SLR” category in the 
SB-80DX, SB-28DX, and SB-50DX manuals.

i-TTL flash control can be used at ISO sensitivities between 100 and 
12800. At values over 12800, the desired results may not be achieved 
at some ranges or aperture settings. If the flash-ready indicator (

M) 

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 (CLS-compatible flash units only).

When an SC-series 17, 28, or 29 sync cable is used for off-camera flash 
photography, correct exposure may not be achieved in i-TTL mode. 
We recommend that you select standard i-TTL fill-flash. Take a test 
shot and view the results in the monitor.

In i-TTL, use the flash panel or bounce adapter provided with the flash 
unit. Do not use other panels such as diffusion panels, as this may 
produce incorrect exposure.

In exposure mode P, the maximum aperture (minimum f-number) is 
limited according to ISO sensitivity, as shown below:

4

4.8

5.6

6.7

8

9.5

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.

Noise in the form of lines may appear in flash photographs taken with 
an SD-9 or SD-8A power pack attached directly to the camera. Reduce 
ISO sensitivity or increase the distance between the camera and the 
power pack.
