As I understand it, metadata is not 100% reliable for Hugin. But what
are the main reasons ?
Not speaking of phones...
First of all hugin originates from panotools which was made in the
1990ies, when there where almost no serious digital cameras. So
thankfully hugin doesn't need EXIF data at all.
Standard EXIF doesn't contain the lens type (fisheye or not). That would
eventually be in the Maker Notes, but not for all lenses and cameras.
Manual lenses don't provide EXIF data since they don't have electrical
contacts.
Even lenses with electrical contacts don't provide exact data, since in
most lenses there is a simple electro-mechanical encoder which works in
only few discret steps for focal length (in a zoom lens) or focus
distance. Cheaper lenses don't even provide focus distance.
EXIF doesn't contain any information about the lens distortion. This
might vary from lens to lens of the same brand and type anyway, so not
even lens databases provide reliable information.
In short: EXIF data isn't reliable at all. Why trust it if all necessary
data can be calculated from the image overlap?
