Hi there,
OK, so the current version of hugin on linux copes with these fine exept
it produces lines like these:
ERROR: 17:53:18.522022 (Panorama.cpp:126) getPTStringParam(): could not
find string param n in line: o f0 y+0.000000 r+0.000000 p+0.000000 u20
d0.000000 e0.000000 v70.000000 a0.000000 b0.000000 c0.000000

As far as the EXIF Info is concerned, the camera info gives a focal
length of 7.1 mm but does not have a crop factor so hugin does the
following:
ERROR: 17:57:35.534655 (PanoramaMemento.cpp:157) readEXIF(): EXIF does
not contain sensor width, assuming 36 x 24 mm film
(hence the 130-degrees) 
PTLens database shows 3.933 as the crop factor to use (equivalent focal
length ~28mm). By the way, at the wide angle you are using, it might be
worth running the photos through PTLens first to correct the
distortions, or use a = 0.013182 and  b = -0.036019.
All of this aside, I have attached an updated .pto that seems fairly
accurate

Doug
