Hi-Sync mode for Nikon has to be set up in the camera settings.
Set your Nikon camera to the Auto FP flash mode in the custom settings menu.
The Skyport Plus HS will then automatically engage the HS mode when you raise the shutter speed above the normal flash sync speed.
To set the camera to the Auto FP flash mode go to:
- Custom Settings Menu (Pencil)
- e Bracketing/Flash
- e1 Flash sync speed
- choose either 1/250s (Auto FP) or 1/320s (Auto FP) depending on your camera.
For a Nikon D4, set it to the 1/250s (Auto FP) setting and (as shown below) for the Nikon D810, you can set it to the 1/320s (Auto FP) setting.
Leave the cameras in this custom flash mode all the time.
