Technical Notes
•
The SB-700 supports AF-assist illumination with 24–135 mm AF lenses.
During viewfinder photography, AF-assist illumination is available with
the focus points highlighted in the illustration.
•
Depending on the lens used and scene recorded, the in-focus indicator
(
I ) may be displayed when the subject is not in focus, or the camera
may be unable to focus and the shutter release will be disabled.
•
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, do not use any form of flash panel (diffusion panel) other than
the flash unit’s built-in flash panel or bounce adapters provided with the
flash unit. Using other panels may produce incorrect exposure.

compensation selected with the optional flash unit or the [ Flash control ]
item in the photo shooting menu is added to the flash compensation
selected with the
