Ho! For pictures with near-infinity focus, lens nodal points
are pretty irrelevant for multi-part panoramas - just use the
camera tripod socket! More important is planning your angles
so that symmetrical and similar crops can be made in the
separate images, otherwise detail near the tops and bottoms of
the images will not match. As to distortion, a moderate amount
of barrel distortion should help since you are trying to
approximate curves with straight line sections, but fisheyes
will not work unless you use very narrow vertical sections of
the separate images.
Hope this helps.
