HSS with C6II + Jinbei Porty 1200 + Pentax 645z

Hi! i'm using the cactus v6 II with some different Systems and all works fine :)

Now, i have the Pentax 645z and we all know, the Sync is only 1/100 for great results. I'm using the Jinbei Porty 1200 (HSS) for Outdoor. Itäs possible to flash 1/400 or 1/1000, that's not the problem. But the photos are lighter from the middle to the bottom. That's mot much, so i can correct it in Lightroom. Is there a workarround?



  • Yes!  There will soon be a new firmware that will work with the 645Z supporting HSS.

    Please stay tuned!
