Compatible Flash Units

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 (CLS-compatible 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 (minimum 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.

• The SB‑5000, SB‑910, SB‑900, SB‑800, SB‑700, SB‑600, SB‑500, and SB‑400 provide red-eye reduction in red-eye reduction and slow-sync with red-eye reduction flash modes.
• “Noise” in the form of lines may appear in flash photographs taken with an SD-9 or SD-8A high-performance battery pack attached directly to the camera. Reduce ISO sensitivity or increase the distance between the camera and the battery pack.
• The camera provides AF-assist illumination as required. AF-assist illuminators on optional flash units will not light.
• 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 camera display.
• In i‑TTL, do not use any form of flash panel (diffusion panel) other than the flash unit’s built-in flash panel or supplied bounce adapter. Using other panels may produce incorrect exposure.
