        Sigma LensType values are hexadecimal numbers stored as a string (without
        the leading "0x").  Decimal values have been added to differentiate lenses
        which would otherwise have the same LensType, and are used by the Composite
        LensID tag when attempting to identify the specific lens model.

        are less than consistent about their metadata formats.
