I start this thread because I found on the net a link giving detailed infos for the Samyang 8mm fisheye CS lens
and in special it shows an image with the exact location of the NPP for different pano settings:
Source: http://michel.thoby.free.fr/SAMYANG/Ear … eport.html
how to shave it: http://www.autopano.net/forum/p56419-20 … -29#p56419
perhaps images for other well used lenses are around and could be posted here to create a sort of central point for this information...
Liebe Gruesse,
Georg

EDIT 11.6.2010:
explanation of the Samyang picture:
2 x ß angel = rotation angle
NPP 60: fov = 120 (60 left 60 right to the middle axis)
(if you follow allans link from post #3 to nodal ninja page you can find link to http://www.johnhpanos.com/epcalib.htm with an link inside to Michael Thobys http://michel.thoby.free.fr/SIGMA8mm/Al … 20Beta.jpg (explainign the values for an sigma fisheye...)

I came across this page on the NodalNinja website which has lots of values for how much to setback / offset the camera on the panohead for various camera / lens combinations.
http://www.nodalninja.com/support/camerasettings.html
The webpage has the following notification, but I suppose it is ok to provide the link.

Hi,
I'm trying to find OSP for Samyang and D300 on NN5.
Through other user's I started at LRS at 60 and URS at 97. However, I'm still testing for OSP / NPP.
Here is an image of my tripod. I'd like for you guys to take look and tell me, if any adjustments are necessary. Exposure of these shots was not the best, but it should be sufficient to see.
It's 6 around for purpose of evaluation. Otherwise, I shoot 4 around.
Thank you!

The bottom right hand side looks longer edged than the others.
Have you tried the Nodal Ninja forum for an answer? This tutorial on how to locate the NPP rather than zoning on two differently spaced verticals may also help

It seems to me that I found NPP, but center of my lens is

That is tutorial that I tried to follow. Spent whole day playing around.
Here is my last attempt for today. Please tell me what am I doing wrong.
Thanks!

When determining the NPP/OSP two factors are most important:
1. To get the LRS (lower Rail Setting) correct.
2. To have the camera sensor plane at 90 degrees to the upper rail.
Looking at your image - I'd say one or both are not correctly set.
As Hans Nyberg has demonstrated the URS is far less critical.

Thank you!
I'll work on it some more adhering to your pointers. Let you know soon.
Where can I see Hans Nyberg's demo?

Hi,
Very interesting stuff on this forum, but for now I need to keep it simple and then make a progression into technical niche.
Here is my last attempt for today. Thank you for looking.
