Sony A7III + hvl-f45rm problem HSS

Hello

I have problem with HSS and TTL on my Sony A7III + hvl-f45rm.

If I set speed for example 1/2000 I have lines on my photo.

With 1/250 is all OK.

If is e-Front Curtain Shut. = OFF, then I can use for example 1/8000 without lines on photos.

Is it OK? Can I not use e-Front Curtain Shut. = ON with HSS?

Or where is the problem?

Thank you.

What is the function of the electronic front curtain shutter?

So, if I use:

Sony A7III + Sony FE 85mm F1.8 + Sony hvl-f45rm + 1/8000 + F1.8 + flash ON

I must turn OFF e-Front Curtain Shut.

Do I understand this correctly?

Thanks

Peter

Yes, because otherwise the problem of Rolling Shutter presents itself to you.
