Cactus V6IIs + Sony HVL-F60M Flash + Sony A6300 - Problem shooting HSS
What I want:
I want to manually control the power output of the strobe when mounted off-camera at shutter speeds above the camera's max sync speed. The target shot is outdoors in bright sunlight, wide open aperture, no ND filters, low ISO, and high shutter speed - classic HSS.
I do not want the camera/flash to automatically decide the power settings. I want control of the situation!
Cactus literature and camera store salesperson both say this will work with my camera/flash setup.
1) Cactus V6IIs with latest firmware + Sony update
2) Sony A6300 and Sony A7Sii with all firmware updates applied
3) Sony HVL-F60M Strobe unit (The strobe supports HSS and works fine when mounted directly on the camera)
I have tried every possible setting on the camera, the strobe, and the Cactus V6IIs to get this to work properly. If the flash does fire, it usually causes banding when the shutter speed is above its sync speed meaning it isn't working properly at HSS. The flash appears to fire at high shutter speeds but I have no power control.
Can anyone, "ANYONE", help? Before you ask, yes, I have read the instruction manual and looked on-line. I'm ready to box them up and send them back.
What I really need is a settings recipe for each device that will make this work or, someone at Cactus to tell me that it just won't work.
