I must say I am really disappointed with the Nodal Ninja arca plate. The only markings are on the top of the plate and this immediately gets covered when you put your camera on it. There are no markings on the bottom of the plate to use with the upper arm markings on the NN5. If your thinking about the Arca Plate, I would say don't and just go with what comes with the system.

If there would be marking on the bottom like the CP-2, it might be better but the way it comes is horrible!!! :'(
