The correct focal length is determined by a factor that differs from 
camera to camera. As I understood hugin reads the (real) focal length 
from the EXIF data, converts it to a focal length for a 35 mm film and 
calculates the degrees of view. Is this right?

IF this is correct, then you have to be able to customize the factor for 
the converstion of the focal length. As I told you, my images are taken 
with a focal factor of 7.13 mm (i.e. 34 mm compared to a 35 mm film), 
because the factor for my camera is 4.77. Hugin converts the focal 
length to 38.601 mm, i.e. a factor of  5.41 is used.
