What I want to know is how do you know when the nodal point is set correctly before you start shooting ?
As mentioned the nodal point can shift With the zoom setting and varies widely from lens to lens even ones that have the same focal length range
I would hope its not just trail and error with the ninja
once you determine where the nodal point is for a fixed focal length lens you dont really need a ninja can easily make your own mount for a fraction of the cost
problem is camera and lens manufacturers dont mark where the nodal point is or even have any kind of documentation showing were it is .... at least they never used to

I saw once that theres a way to find the nodal point using a lazy Susan and some pencils I'll have to look for that again
