Rozumiem ,
pod windowsem nigdy tego nie sprawdzałem, może ta opcja wynika z faktu możliwości podpięcia obiektywów FX pod DX ale tego dokładnie nie wiem.
Pewnie trzeba poczytać specyfikację EXIF jaką stosuje Canon

Sprawdzilem i na wikipedii pod hasłem EXIF jest link do definicji Kodaka. Jest tam pozycja 4198 "Focal length in 35 mm film".
Wszystko jest. W linuxie jak najbardziej też
