I have a camera filling the tag Exif.NikonAFT.AFFineTuneAdj. Camera for example shows -9, output of exiv2 is 247.
The only other tag of type SByte I have found is Exif.Pentax.Temperature.

Thanks for reporting this, Norbert. Can you provide an image file for me to reproduce this. I'd like you to give us permission to reuse the metadata in your file in our test suite.

I've got the file you provided when we discussed something about this a couple of years ago. http://dev.exiv2.org/boards/3/topics/1337
Here's what I see:

I've set the status to Resolved/100% and, if nothing else arises, this will be closed prior to shipping v0.26.
