Sony A9 III A9 III flash synch speed stays at 1/500

[Ericandpam]

I have an A9 III and is supposed to synch at ALL shutter speeds. When I shoot on manual, all shutter speeds are available but as soon as I put my Godox flash trigger in the hotshoe, the maximum shutter speed only goes to 1/500. How do I get faster synch speeds? Thanks

Put the trigger into highspeed mode - Godox call it highspeed Sync

On my X-Pro trigger pressing the sync button turns it on and you get a little H symbol with a flash at the top of the screen

No, that puts it into high speed sync, which means you are not using the A9 III's ability to sync at any speed.

I managed to get a Godox V1 to sync at high speed (all the way to 1/80000). The key thing is to turn on Flash Timing Setting On. Without that, it will cap at 1/500. Then you get to experiment with different delay factors in microseconds. The right delay varies with the intensity of the flash, and I never did work out the pattern.

The cute part is that the Sony HVL-F46RM and HVL-F60RM2 both work without messing with the Flash Timing Setting. I'd love to think that Godox could reverse-engineer how that works. Might only work for their on-camera style flash units like the V1 - getting it to work for mains powered units could be much more difficult.

Looks like Godoz has worked it out! But you have to buy their new flash (V100) to get it. Is anyone really surprised?

Still, now there's a Godox flash which can sunc with the A9 III.
