The Z-Finder Mounting Frame for the Panasonic GH3 camera is specifically designed for a Panasonic GH3 and is not compatible with any other cameras or alternate set ups. It will not work when a battery grip is added to the camera or when the camera screen is articulated. The Z-Finder frame attaches to the DSLR Gorilla Plate V2 with two red Z-Finder Thumbscrews which screw directly into the Gorilla Plate V2. The frame has a rubber coating on the back to avoid scratching and to ensure a clean seal with the LCD screen.
