Description

When the exiv2 0.24 and 0.25 tools/libraries process data from photos taken with a Canon EOS 6D body, firmware 1.1.6, with a Tamron 28-300mm
F/3.5-6.3 Di VC PZD A010 lens, it seems to detect the lens as a 'Canon EF 90-300mm f/4.5-5.6 USM'.

exiv2 -pt FILENAME | grep -ai lens output is:

It may have been incorrectly detected by v0.24 and v0.25, however it seems to be correct with trunk.
