#3. "RE: Can I use a sb-80dx in slave mode with a D700?" In response to In response to 0
The SB-80DX has a built in optical slave mode that can be set to non-TTL Auto mode or Manual flash mode. The D700's built-in Speedlight or on camera Speedlight must be set in Manual flash mode or non-TTL Auto flash mode. I would also recommend having the camera in Manual exposure mode and Manual ISO as well. Good Luck and Enjoy your Nikons!
