I just found this motorised pano head http://www.thegadgetworks.com/index.html
Unfortunately for this model there is no way to adjust the vertical nodal point.
We all agree with youâ€¦ NPP means (No parallax Point)
Just a small adjustment in the initial theory, there is almost no NPP to take care of when a tele lens is involved, just because NPP is a ratio with near and far objectsâ€¦
If you are taking a picture at more than 2 to 3 meters awayâ€¦ This NPP rule becomes outdatedâ€¦ why !
NPP is only very sensitive to close and far objects. This can make a very funny perspective result.
Just consider that you are taking a picture from your seat, then turn your head and observe that the window's foreground and window's background are messing up â€¦ don't you !!!
To resolve that geometry perspective point is only a perspective projection's problem â€¦ Get closer to the Windows's view and you'll see that there are no more movementsâ€¦ This is what we call no NPP, No parallax movementâ€¦
Most of the time fisheye and ultra wide angle lens are very much concerned with very precise NPP. Tele lens are a lot less concerned by the phenomenon.
Keep asking and keep wondering to get a picture of the whole problemâ€¦ It can help the whole community
Any way, Thanks for thinking !!!
