About the camera shutter speed and the amount of flash light
About global shutter sync photography
By using the HVL-F60RM2/HVL-F46RM optional Sony flash (system software update required) and a camera with a global shutter type image sensor, flash sync shooting can be performed throughout the range of the shutter speed of the camera. This enables more efficient exposure from the flash-light than conventional high-speed sync (HSS) shooting.
Depending on the camera’s shutter speed setting, the flash level may be insufficient and not reach the manual setting for the amount of flash light. In this case, a low flash lighting amount warning appears on the LCD panel of the flash. Refer to the tables below for the combinations of shutter speed and flash level settings that cause the low flash lighting amount warning to appear.
