PTGui does the same thing for me too. I think something may be wrong
with the way those three fields interact.
Just IGNORE the focal length and focal length multiplier fields.
There is only one important value and it is "Horizontal Field of Field."
For this lens, in portrait orientation, the value is somewhere near
86 degrees. That is, the angle of view across the SHORT side of the
image is about 86 degrees. The other way, it's about 137 degrees.
Just set Lens type to Fullframe and HFoV to 87.
Make sure you are using the ADVANCED interface, and please do
ENTIRELY SKIP the Project Assistant tab. You may also want to try
IGNORING info in the EXIF data (which presumable includes camera
orientation). I swear, all these "automatic wizards" are far more
confusing and more trouble than they're worth.
Note that "87" degrees is just a starting point. After optimization,
the value will be fine-tuned. Check the Lens settings tab. If your
stitched image looks good, save the values to the Lens database and
re-load them each time. Or use "Make Default..." to have these
settings come up automatically for every new project.
