Profoto A1X not working with Pentax 645Z

klaur94 · 12-04-2019, 03:09 PM

Hi!

I just purchased the Pentax 645Z and I am loving it. I heard about it from Jean Philippe Lebbe who used his Profoto A1 flash on the Pentax 645z. (

You Tube

) I have tried using it on the hot shoe but it won't work in manual mode. Does anyone know what I should do? I know it can work - I'm just not sure how.

Thanks in advance!

Try setting the shutter speed to 1/100 sec in manual and see if that works, I find my 645z can be iffy if its at the max sync speed, sometimes it fires sometimes it wont, drop the speed a tad and its 100% reliable
