The Ultimate Map of All Nodal Ninja Lens Ring Stop Plates

Without these plastic stop plates you need to check if the shift in the panorama head clamp is correct to ensure a good no-parallax point calibration. The stop plates are designed to eliminate the need for this check. After you insert them to the bottom of the lens ring they auto-calibrate the no-parallax point on your Nodal Ninja R1, R10 and R20 heads. It works because there is a small hole in each of the plates that holds the security pin on your head. 

The stop plates come in a variety of shapes and sizes, here are some illustrative examples:

Here is a complete listing of all available Nodal Ninja stop plates:

* Note - Google packages: that these rail stops are already included for free when you purchase a Google package from us. You will only need it when you are buying a separate lens ring or if you have upgraded or changed your equipment. 

Note - Compatibility: The above stop plates are compatible with Nodal Ninja R1, R10 or R20 heads which have a security pin that can snap into the hole in the stop plate.
