PBCBGE22r56 Canon R5 & R6 Battery Grip Arca-Swiss type Plate For Flash Brackets, L-Brackets, Handles, Straps

Perfect fit on the BG-R10 grip. There's no way that this plate can twist while mounted.
The PMG plate + PASL3 Bracket Plate Adapter together are much slimmer than the combination of my Spyder plate + Peak Design tripod plate. The Spyder+PD combination was thicker but also not sturdy at all, there are no twist lock pins between them.
I had some concerns that the PMG plate would not fit properly on my Peak Design tripod. On this tripod, not all arca plates fit well. PMG assured me by email that it would fit and they were right.
I also ordered the "SS2P2 Retrofit Quick Release Plug Adapter for Camera Shoulder Straps". If fits really well to the plate and feels very secure. I would like an SSP2 socket on a different position on the PASL3 though, but will explain that in the review for the PASL3.
100% happy! :-)
Ordered from the PMG website and had to pay a substantial amount of import tax (Netherlands). Make sure you take that into account.

Promediagear pays attention to detail and produces solid gear. Once I’ve installed one it their plates, be it a camera or other Arca Swiss plate, I know it’s going to do its job and do it right… One less thing to worry about so I can concentrate on the creativity. Ex-photojournalist turned wedding and even photographer, so I need my gear to work every time. Great stuff from great guys.

Great design and beautifully crafted piece of kit!

I have a complete camera carry strap set up for all of cameras. This is the 3rd I have purchased. The quick disconnect is the bomb! The shoulder strap has two disconnects allowing the shoulder pad to be removed. I have matching quick connects on the shoulder straps of my Lowelpro bag enabling me to attached the strap directly to my shoulder straps. Now, all the weight of the camera, 100-400 zoom, etc is transferred to my shoulders. This makes all day shoots doable for an old fat man. Since all of my tripods have Arca-Swiss mounts, its a quick disconnect at the plate, and I am in business. I also have a small Arca-Swiss on my Canon 100-400.

I have these plates on a Canon 5DsR, a fully rigged BlackMagic 6K, and now on my Canon R5. It works flawlessly on all three.

This fits the both the camera and my hand perfectly, I love the ergonomics of its design and I completely trust the security of it when attached to the camera.
