Hi, I have a Canon PowerShot S120
Using exiv2 0.24 (libexiv2-13 0.24) on my Debian box I can read the Exiv metadata. Exif.CanonSi.SubjectDistance is reported without measuring unit, beacuse "units are not clear" (as reported here http://www.exiv2.org/tags-canon.html).
I think that unit is centimeters; I shot several photos in manual focus mode, setting approximately the focus on the LCD scalebar. The values registered into the Exif tag are:
zero -> 7 10 cm -> 14 20 cm -> 27 50 cm -> 54 1 m -> 102 2 m -> 200 5 m -> 606 infinity -> 6553
Reasonable values are also indicated for photos taken in auto-focus mode.

Simple fix. Subject distances are now shown in meters.
Translation templates need to be updated during the release process though.
