Cactus V6 II with Hensel studio flash

henryx

I got a pleasant surprise today as I managed to use HSS with my Hensel Expert Pro 500 Plus studio flash via Cactus V6 II and Fujifilm X-T2 camera.  The receiving Cactus V6 II was plugged into the Hensel flash with a sync cord, the transmitting Cactus V6 II with "forced HSS on"-setting was on top of the camera. I was even able to control flash power on the Hensel Strobe Wizard Plus radio transmitter which was placed on top of the transmitting Cactus. There was slight banding on the edge of the photo every fifth or sixth shot, especially at the highest 1/4000s and 1/8000s shutter speeds. I tried the same setup with my Hensel Porty portable battery flash system (Hensel Porty L1200 + Hensel EH Pro Mini 1200 P) but HSS 

didn´t work. There was heavy banding and ghosting but the photo was never totally black. Would there be a way to make it work? By the way, I have achieved HSS with these Hensels by firing a Nikon flash on a Nikon camera  (both on HSS) into the optical slave of the Hensels...

Have you tried removing Hensel's own transmitter from the setup?

Since the Hensel transmitter only has a single pin hot shoe contact, meaning it's not system specific, nor can it activate a HSS function on the strobe, all you rely on is the flash duration on your Expert Pro 500 and Mini 1200 P. 

Despite mounting Hensel's transmitter on the V6 II system there could be slight delays, but the main reason for black bands is that the flash duration is not long enough. It needs to be 1/100s at t0.1 or longer in order to cover the entire frame of the image.

Again, it depends on the strobe's flash duration.
