I have find some time to determine the optimal setting for Sigma 8mm F3.5 Canon and Nikon on R10 7.5 deg.
Here is a table to show the settings.

I would appreciate if users can test the validity by making a pano using my value(s).
I will make integrated rail plate for selected tilt angles. I will give 10 free copies for responders (one each) of each mount. $10 in value.

R10 7.5 deg, Sigma 8mm F3.5, 4 shots around.
for Nikon, LRP-45X value 1.4
for Canon, LRP-40 value 0.85
Can any one confirm the Nikon setting?

I found 1.2 to be closer with Sigma 8mm Nikon on LRP45x
When finding NPP I found also you get different readings at different locations of lens so I used center barrel of lens to get the 1.2
This isn't pixel by pixel comparison in photoshop.

That is the problem with NPP settings. it depends on the location. I concentrate on the horizon.
