To create a spherical panorama, the only important part is to rotate the zero paralax point of the lens around a fixed point in space. It is not necessary to level the adapter because the full sphere is captured.
The plane of the zero paralax point of the 7.5mm fish eye lens is between the front barrel and the hood.
This is a custom adapter specific to the Panasonic GM1:
This is the first post of a series to create 360°x180° panoramic images using the cheap 7.5mm Micro 4/3 Fisheye. This lens is a 7.5mm FullFrame Fisheye (180° diagonal view) for the Micro 4/3 lens mount with aperture and distance ring. The lens is fully manual with no electrical contacts and require the camera to be in A mode and the setting 'shooting without lens'.
To create 360°x180° panoramic images it is best to use a Fisheye to reduce the amount of images needed. Only 6 images are required using a FullFrame Fisheye for the spherical Image: Four images horizontal, one up (Zenit) and one down (Nadir).

Using a DIY Arca-Swiss compatible plate to attach the camera to the Nodal Ninja panoramic adapter:
The red line marks the zero point to rotate the lens around. The adapter needs to be adjusted accordingly:
Here is todays hardware project for the Panasonic GM1:
