Global shutter sync photography
By using a combination of this flash unit (flash unit software version 2.00 or later) and a camera equipped with a global shutter image sensor, flash photography can be synchronized with the entire range of shutter speeds available on the camera, enabling more effective flash exposures than conventional high-speed sync photography (HSS).
Note
-
If you set the shutter speed of the camera faster than 1/10000 and take a photo, brightness and colors may vary.
-
With a camera equipped with global shutter image sensor, the HSS icon is not displayed on the camera regardless of whether the high-speed sync setting is [ON]/[OFF].
-
When the flash unit and camera are connected with an off-camera cable (not supplied) to perform photography, then instead of global shutter sync photography, it is performed by the conventional high-speed sync photography, so the distance the flash light can reach is shortened.
-
During multiple flash photography or with the camera flash mode set to rear curtain sync, the shutter speed of the camera is limited to the flash sync speed.
-
If the shutter speed of the camera is set faster than the flash duration of this flash unit, the flash power level may not reach the set value. In such cases, the low flash power level indicator is displayed on the flash charging icon of the camera.
