Magnet rotator and simple holder for creation of your panoramas. Free rotation 30, 60 , 90 180 degree on a manfrotto plate or direct connection possible. The 10 x 4 mm magnets and a 20mm bolt to your camera are the ones to get hold of. Also the magnets are fixing the camera and by pulling and turning easy to detach. Works great but beware of magnetism and memory cards! (The lensholder is also on my collection)Press the magnet in the plates check plus and minus before placing it's hard to get the magnets out! If you need 30 degree only skip a hole so you need 3 magnets in a set. There are three sets one for a manfrotto plate and opposite a camera connection. Alse a simple plate for a lensring or bracket tripot collar.
