2x cactus v6's and 1x cactus rf60 flash for a pentax k-s2
I recently bought 2x cactus v6, and 1x cactus RF60x flash, and a pentax k-s2. cannot for the life of me work out how to get them synced. I read somewhere pentax k-s2 doesnt have wireless flash abilities but should this matter if the v6 is on both camear and flash? help would be much appreciated.
