I used this mount adapter for a Profoto A2 with the BBX2 flash bracket. worked fine.
We should expect no less from PMG, but this thing really is perfect. Super quick on/off with the standard thumbscrew, and the flats position it for a secure, no-rotation fit. Oh, and thanks for choosing stainless over brass. It just looks so much better with all the other stainless hardware on the Boomerang. I use it with the Godox AD100, but the AD200 mounts up just as securely, if you can stand the extra weight.
I LOVE THIS. The stud is just what I needed and stays put thanks the the sides of the stud fitting perfectly in the inset space (with the squared off sides).
bought this as a foundational mount for a boomerang bracket, so the review is really for the entire system. At first I thought it was pricey, having to purchase everything in piece parts to get an entire solution. But once I received everything and put it all together the system is pure magic and worth every penny. Lightweight, flexible and well thought out design. And it is compatible with my Really Right Stuff bullheads, which means I don't have to swap brackets midstream. All in all really well designed and makes getting flash up and off the hotshoe much more achievable and with less wear on the shoulders and back. Marry this with a proper harness system and you are good to go for an 8 hour event.
Makes it possible to shoot with a ProFoto B2 mounted to your Boomerang flash bracket. Functions perfectly.
