Originally posted by blackcloudbrew Well, as it's been more than a year since I got my gear out, it took me awhile to remember how to make things talk to each other. I have the Cactus RF60X flash with the latest firmware A.08 and a Cactus V6II with the latest firmware PEN.A.005. Had to check but I remember updating all my devices firmware in 2000 when I bought the setup. Bottom line here is that it works just fine on both my K-1II and 645z. I haven't done test with my 540FGZII as that's another recall of forgotten memory issue for me. I kinda recall that the 540 + Cactus was a bit touchy, but again I'm relying on memory here. Anyway, that's what I've seen here. Not going to worry about the 540 / Cactus combo though. YMMV
Thank you very much Tim, for spending the time to check and with the detail too - it's really appreciated. Your synapses will have appreciated the workout too
Now that niggling worm, that's the 645Z, will reappear and start working on me ...
Thanks again ...
