The Zacuto Z-MFS32 Z-Finder Mounting frame is to use small body DSLRs with 3.2" screens such as the Canon 5D MIII and Nikon D800. This Frame will not work if you are using a battery grip with your camera. For that you will need a battery grip frame for 3.2" screens, which Zacuto is still working on. It also working on the 3.2" frame for Tall Bodied Cameras and a 3.2" Adhesive Frame.
The Z-Finder Aircraft Aluminum Frame must be used in conjunction with the Gorilla plate. The Z-Finder frame attaches to the Gorilla plate with two thumb screws; the Gorilla plate is attached to the bottom of your camera. The frame has a rubber coating on the end which stays against the LCD screen with pressure. The connection between the Z-Finder and frame is a snap fit. The Z-Finder snaps into the frame and can quickly snap off for going between video and photos. To release the frame from your camera, you must un-do the thumb screws and slide the frame off.

It gives a tiny bit more view of the screen, but to be honest on the 5DMKIII things are so tight around the screen, that fitting a bigger frame would have compromised button access. This screen uses the same viewfinder (Pro), so if you upgrade your camera from a 5D mkII or other, all you have to do is upgrade the frame. The frame only touches the bottom nuts at the edge of the mounting slots, it is a little unstable as the metal flexes some when you pull the viewfinder, I suggest dismantling by pulling from the bottom.
