Sony A7ii and HSS question

[photopappa]

Hello all im a new to Sony user and have a strange situation that I dont know a work around for.  I have been shooting OCF for a few years so this has me stumped. When shooting OCF on my a7ii with camera set to fill flash there is such a delay to fire a shot that I often miss it.. regardless of Fstop or shutter speed.. but.... if I set that to rear curtain sync its immediate and thus seems backwards.. this would be fine as is works but then my max shutter speed is once again 1/250th... anyone have a clue whats happening or what i can try differently. Im a wedding and portrait photographer and cant work with a delay in shutter release.. equipment listed below 

 

Sony a7ii

Sigma Art 35 f1.4 Amount adapted

1 Godox AD360

1 Godox Li-ion powered speedlight and a second on the way

 

Thank you in advance for any and all help.. I try the all knowing Google first but nothing

You offer almost no information, as if all users

are going to use the same procedure, and so

would follow your actions and results. But with

so many variables, thaz not the case. And so

you'll hafta fill in the gaps and be more explicit

as to all the variables.  

 

The remark about shutter speed sort of implies

your problem involves FP mode. Then a switch

to 2nd curtain synch and things are different. If

you think about it, 2nd curtain synch can never

be in FP mode ... so, two different behaviors.

  

Sony manuals do sukk, but they're not toadally

useless. The PDF version is the same manual

but cuz it's automated, it's less frustrating and

that sometimes helps you figger stuff out.

How are you triggering your flash?

 

I presume, being off-camera, that it's some wireless trigger, which could well be where the problem lies as it will depend upon how that trigger interprets the Sony flash protocol.

It could well be sending a 'fire' signal at the start of the shutter sequence, rather than the end, for rear sync.

 

Also, not all triggers and flash units will support HSS for Sony. Again, it depends upon the protocol used and how it is implemented.

 

Just in case, although I appreciate you are experienced, is your camera set on 'rear sync', or 'slow sync'? In days gone by, when there wasn't as much control or choice, people would often confuse the two, and not all cameras offer both.

It would certainly make a difference to the timing of the flash, though.

Go to the menu, remove red-eye detection..... solved!!!!!!

I have been having this same problem, and yes! turning red eye off seems to have solved the delay, but why of earth would red eye reduction make a difference on flash/strobe-shutter delay?
