General Nikon Operational Considerations
The following operational considerations apply to all Nikon cameras unless otherwise noted.
Flash Sync Speed - Custom Camera Setting
When using the D750 and ControlTL radios the camera's "Flash Sync Speed" setting must be set to "1/200 s (Auto FP)." This setting can be found in the "Bracketing/Flash" Custom Settings menu. This is different from other Nikon cameras, which require a Flash Sync Speed setting of 1/250 s (Auto FP).
