my bad my bad
the use_** options are to register in database and so it's not for extra entries

$conf['show_exif_fields'] = array(
  'Make',
  'Model',
  'DateTimeOriginal',
  'COMPUTED;ApertureFNumber',
  'FocalLength'
  );
should be ok

Use Localfiles Editor
And if you don't put others like DateTimeOriginal they will be not displayed because iy completely overwrite default config

hmm tricky
that would need a custom small plugin using a prefilter to remove those two last characters

Yes, [extension by maple] EXIF View was designed exactly for this :-)
