In the past few months I have been punishing myself to perfect my shooting technique and stitching process. I have made successful attempts in finding the NO PARALAX POINT for my lens which is the (Samyang 8 mm f3.5 fisheye CS lens) and the guide i fillow is this one:michel.thoby.free.fr/SAMYANG/Early%20test%20repor...
But i am still not getting the PERFECT stitch. My problem is I don't' understand if I still need t work on the actually pupil entrance or is there a problem somewhere else. SO i have been working more on it and moving it back and forward and doing tests.
In the result i found out that my zenith causes problems now. Let me explain.
I shoot 6 shots at 60 degrees each and right after i point my camera up and shoot a zenith, then down and do 2 nadir shots and one handheld/ or tripod shot of the area.
The 6 shots, when stitched are PERFECT. but as soon as I add the Zenith or the Nadir, i get aberrations and Paralax.
Please advise what I should be doing since I think I am going in circles.
Could it also be that I am too close to my subjects? Because when i am doing testing in my room its small and i ALWAYS get errors.
What when you stitch the 6 shot plus zenith? So without nadir?

Octavias has disappeared into a cloud of logic Hans.....but I can say for sure that some FE have no true NPP....because the NPP is dependent on the direction of entrence of the lightrays as can be demonstrated using a laser pointer. I don't think the Samyang 8 has such a charisteristic:
