Oh my goodness! Few products have ever been so obviously well thought out and executed. It’s perfect. I’ve tried several different solutions and this is the first one to get almost everything right. It fits the GX9 correctly, provides access to the card/battery hatch, is sturdy metal, includes an integrated arca Swiss plate that doesn’t interfere with attaching wide barreled lenses like the Nocticron, and has an additional threaded connection for an L-plate when you want one. Highly recommended!
