Image::ExifTool::Sony - Sony EXIF maker notes tags

=head1 SYNOPSIS

This module is loaded automatically by Image::ExifTool when required.

=head1 DESCRIPTION

This module contains definitions required by Image::ExifTool to interpret
Sony maker notes EXIF meta information.

=head1 NOTES

Also see Minolta.pm since Sony DSLR models use structures originating from
Minolta.
