LF1300-EWf Features

Shutter-linked AUTO OFF function
On-board incident light sensor detects flashing from built-in flash/external strobe to trigger this feature to shut off the light in sync with the shutter release and turns ON again automatically to avoid exposure of the light itself on an image or backscatter by not illuminating suspended particles.

Shutter-linked AUTO OFF function is controlled by the red Selector Ring LF. You can use the function for still images or deactivate Shutter-linked AUTO OFF function to use the LF1300-EWf as a video light to avoid unintentional cut-off by neighbor’s flash.

Cut-off time of this function is only 0.2 seconds not to lose your subject when using this function.
