I will be freezing the ball with 1/10,000 second duration flash pulse from my QT1200 strobes, not with my shutter speed, same as this guy is doing, and my R3 will flash sync at 1/250 in EFCS mode. Using flash and then ALSO trying to use fast shutter speed is misunderstanding entirely what you’re doing.
good luck trying to freeze a ball in the air with 120 or 250 lol , also 250 will be high speed sync
There are multiple cameras on the market that can sync at 1/250 without switching to HSS.
