I am newbie in photography and HVL-F60RM flash is my first ever had. As I was reading about flash high speed capabilities thought it will work shooting set on fastest available camera speed 1/8000 on A7SM2 silent mode.
However, switching on to silent mode HVL-F60RM becomes unavailable.
What I am doing wrong and is it possible to somehow use HVL-F60RM while A7SM2 set to silent shooting mode?
