Quick question. How much power on average do you all think you are losing on hss? I realize this isn’t a Pentax specific question but my guess is I’m losing about 2 stops.

Hey guys,
Finally my 45-85 arrived today and hss worked immediately, upto 1/4000 (with very slight darkening of the top of the frame) with a Vii on the hot shoe, and one into the sync port on the AD600.
Looking forward to trying the 35A when it shows up.
I have yet to try any other trigger setups, but hoping to try a Profoto b1, a Godox canon trigger and the ft16 setup this weekend.
Thanks for all the help!
-Tony.

Mcgregni looks like that is my issue. I’m using an adapted mamiya shift lens. I’ll try it again this week with an af. ---------- Post added 04-22-18 at 04:30 PM ---------- I am using PEN.A.001

Thanks guys. I have the firmware all updated.
One thing that crossed my mind, is that i am trying to get this to work with a fully manual lens, and that hss requires lens communication to the body.
I’ll try an af lens and see if that gets me anywhere.

There is no correct answer this question. Every situation is different.

I have been racking my brains trying to figure this out, and have not yet been able to find a solution.
I recently bought a pair of Cactus Vii to work with my pentax 645z, and Godox ad600, and no matter what I seem to try, there seems to be a communication error.
I have tried-
Cactus V2 with Godox ad600, using the x1N. I know this setup has not been proven to work, so I purchased the Godox FT16/USB receiver setup as described here, and tested setup as reccomended. HSS Pentax 645Z Godox 600 – Mark Kitaoka Photographs
In addition I have tried Profoto B1, with a Cactus Vii and Profoto remotes, both Canon and Nikon as described here: You Tube |

also tried a cactus vii on camera, and another connected through sync port.
I must be missing something. With these settings.
(c) pentax
(f) manual or auto
I get nothing. The camera won’t fire over 1/125, and in fact sometimes becomes locked at 1/125. Wont allow me to drop the shutter even below that speed.
Anyone see something I could be missing? I have updated the firmware on both cactus units.
