Well, with exiftool, I get : Lens Type : Canon EF 75-300mm f/4-5.6 IS USM or Sigma Lens ... ... Lens Info : 18-300mm f/0 Lens Model : 18-300mm Lens Serial Number : 0000000000 Lens : 18.0 - 300.0 mm Lens ID : Sigma 18-300mm f/3.5-6.3 DC Macro OS HS Lens : 18.0 - 300.0 mm (35 mm equivalent: 28.0 - 466.3 mm)
which seems to be correct... with exiv2 : Exif.CanonCs.LensType Short 1 Canon EF 75-300mm f/4-5.6 IS USM Exif.CanonCs.Lens Short 3 18.0 - 300.0 mm Exif.Canon.LensModel Ascii 74 18-300mm Exif.Photo.LensSpecification Rational 4 18/1 300/1 0/1 0/1 Exif.Photo.LensModel Ascii 9 18-300mm Exif.Photo.LensSerialNumber Ascii 11 0000000000 which is confusing because the Type is only on the Canon, not "or Sigma" but other lens data are related to the Sigma. In darktable, it is wrong also because it is the LensType which is reported.
