The Ultimate Map of All Nodal Ninja Lens Ring Stop Plates

Last updated December 2021

Nodal Ninja stop plates are designed to auto-calibrate the no-parallax point on your R1/R10/R20 head for your specific lens ring and workflow. 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. 

** 104B - Intended for the R10 head with a custom 30mm top clamp.

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.
