I have a flash sync question on the GFX Cameras. They all appears to have 1/125th flash sync speed. I own profoto flash equipment and really enjoy using flash photography for portraits and also other work. I find flash photography enjoyable.

Anyways, I also know that you can use HSS using the profoto equipment but I also understand the great losses of light using HSS. So outside flash, to reduce the ambient light do GFX owners really have to use filters to not use HSS?

So you have Fuji that has a low flash sync and Hassellblad X2D which has great flash sync but terrible focus problems. Is there a MF option that combines the two ?

I want to join the MF club but am finding road blocks with both systems or please explain what I am missing here ?

If you use strobes a lot outdoors I would recommend the Hasselblad system.
Leaf shutters give you a lot of advantages over HSS.

You need very powerful strobes with HSS if the ambient light is bright and you want the strobes to be more than a few feet away.

For portrait shoots the AF of the X2D with the latest firmware should be fine.
Just don’t expect FF AF performance from MF. My Nikon Z9 is leaps better than the GFX100 I used to own.

I have yet to see a hasseblad shooter shooting outdoor portraits with strobes. I want to see what strobes they use (technically one could get away with much lower power strobes), how the final output looks like in real life (no charts, graphs etc). So far I have asked this a few times and nothing.

BTW - I shoot strobes outdoors 100% and 1/125 hasn't been an issue. I have power to spare with 2 600ws strobes. I do wish Fuji had a LF lens or two for people like me.

If you have powerful strobes you can overpower the ambient light.

The power of using a leaf shutter is the reduced requirement for flash power.
This means you can use smaller, lighter strobes when walking about outside.

The 600Ws strobes are large and heavy.
If you can instead use a 100Ws strobe with a leaf shutter camera you save a lot of weight and bulk.

My Elinchrom ELB500 has two heads.
If I split the power equally between the two I get 250Ws per head.
That is equal to 2x 1200Ws heads using HSS.
Total weight is around 3500 grams.

Once you start using HSS you will loose around 2-3 stops of light at higher power settings.

You loose 1.5 stops when using entering HSS. After that no more as each increase in ss, I am also opening up the aperture. My cheap godox AD600s I put them on a wheeled avenger or mathews. No need for any sand bag then. Just roll. I would like to have a LF lens but so far nothing from Fuji. Other option is global shutters but maybe it is still 7-8 yr before showing up in MF camera.

Well, you do loose more light, it's just that you compensate by opening your aperture.
The wider aperture means your strobe needs to work less hard
