pentax K-5 RF60X no HSS-PTTL
I'm am using A001 firmware on all of my devices which are Pentax K-5 powering a V6ii with Pentax af540 and a cactus RF60X
The V6ii with the pentax af540 will allow HSS
The RF60X shows black frames or will not sync the flash to the camera I am convinced its user error but not sure what I am doing wrong?
Thank you for your help in advance
