6.4 Sincronización de alta velocidade (HSS)
The YN568EX III supports High-Speed Sync (HSS), allowing you to use flash at shutter speeds up to 1/8000s. This is useful for freezing fast motion or using wide apertures in bright conditions.
This image illustrates the capability of High-Speed Sync (HSS) to freeze fast-moving subjects, such as water droplets, at shutter speeds up to 1/8000s.
6.5 Wireless Slave Mode
The YN568EX III can function as a wireless slave unit, triggered by other flash units or camera's built-in flash. It supports optical transmission wireless slave modes (S1/S2) and is compatible with Nikon's optical master units (e.g., SB-910, SB-900, SB-800, SB-700, Nikon internal flash). It can also act as a master unit to trigger other YONGNUO and C EX series speedlites (excluding YN585EX) across 4 channels.
