New version stronger! Sketchup file included. 6 or 3 step panorama head to make 360 degree spherical shots. For a sigma 8mm lens but will also work with any other 8mm lens too if diameter of the lens is the same. Works beautiful just using some minor force to rotate and it disengage too by cantilever the camera. Manfroto plate is included.
You need 12 strong magnets 5x10 mm and 2mm x 30mm bold and nut, and a screw insert for a big to small to screw in the bottom plate which will also fit to a manfroto plate if needed. First try to fit all magnet clean the holes if needed than place al magnets an force them together and leave to dry (+ and - direction!). Use the plate with only hole and fix it in the hexagon gap use glue or a bolt. Clean the edges and place the clamp grips on top of each-other an use force to slide them in. Use tape or a bike inner tube to use around your lens to protect than fit the clamp by and fit your lens and use the bold and nut to fix it. Nodal point is where the lens cap hits the notch. Ready to shoot! I use it in combination of a Canon 5DS others wil work too.
