Most cameras are designed with its tripod mounting hole positioned perfectly center along the bottom/base of the camera body. However, there are a few cameras that have been designed with the mounting hole off-center, making it difficult to balance onto most gimbals. (See below)
However, one useful solution to this problem is to use a PU-150 Benro/Arca Swiss style QR plate as an extension adapter plate to add more flexibility to your balancing options.
Notes from user Ray Roscoe:
1. Remove the center stop screw so the camera can slide just that bit further.
2. There are 2 small allen screw sin the plate, one needs to be removed tow enable the extension plate a little more movement.
