Metadata of Canon EF-S 18-55mm are not read correctly
Exiv2 reads from images taken with the lens
Canon EF-S 18-55mm f/3.5-5.6 USM
the lens description
Canon EF-S 18-55mm f/3.5-4.5 USM.
This causes for example digikam not being able to automatically apply lens correction to such images. I attach a picture taken with this lens here.
