Field of View (FOV) calculation

[Rhadamanthys]

Presumably the composite FOV value is being calculated from the Exif tag "Focal Length (35mm)".
Some of my cameras support digital zoom which changes the field of view and write a tag "Digital Zoom Ratio" (Names copied from IMatch Metadata Browser)
Would it make sense to include the latter in the FOV calculation?

These calculations are done by ExifTool not IMatch.
You should ask this in the ExifTool forum to see if Phil is able/willing to support this.
