No flash sync / Nikon D850

Hi - new user here. Although i've got focus stacking working without flash ok , I can't seem to get any flash to cooperate.

Set up :

Nikon D850
Sigma 105mm DG Macro lens
Nissin MF18 ring flash (also tried a Shanny SN600SN)
manual camera settings (eg f7.1 , 1/250 , ISO 400)
Autofocus set on camera and lens
Helicon remote V 3.9.1

I've tried switching off live view and also turning to manual autofocus etc but although the flash will then fire , the focus doesn't move.

Any suggestions on what setting to try to resolve ?

It's probable that this boils down to camera body settings, but don't know which one, sorry. If you figure it out, we'd appreciate if you also let us know.

Note that if you switch to MF and have "Activate live when taking a shot" set to "No" in Helicon Remote, then you're truly shooting without turning live view on. If you switch to AF, then live view is required and cannot be bypassed regardless of the program settings. So it sounds like your flash indeed fails to trigger during live view. So it also could be a quirk of this particular flash.

Hi - thanks for your reply.

Ive now tested the Nissin flash with my Nikon D500 and it syncs ok with that and stacks accordingly. I think the non flash sync with the Nikon d850 is around the electronic shutter. Helicon is using the electronic (silent)shutter rather than the mechanical shutter. I do know the D850's own built in focus shift feature won't fire a flash when set to silent shutter (ie electronic).
I will have a look to see if there is a setting to only use mechanical shutter on D850 - unless there is a setting in Helicon which can force a camera to use only mechanical ?

Thanks ,

Hi - in answer to my own question ...... I've now disabled the electronic shutter in Nikon D850 the LV menu and I can now get flash sync as it using the mechanical shutter ! :D
