The EXIF Viewer here:
based on Phil Harvey's EXIF Tool shows Field Of View as a derived field
(not in the EXIF data), and it is available for my Nikon D5000 and my
iPad3, but not for my Sony HX200V.
I don't think there is any difference in the terms - both should refer
to the diagonal field of view. Perhaps modern usage is different?
