Looking at canonmn.cpp in the Exiv2 codebase:
{ 169, "Canon EF 17-35mm f/2.8L"
}, // 0
{ 169, "Sigma 18-200mm f/3.5-6.3 DC OS"
}, // 1
{ 169, "Sigma 15-30mm f/3.5-4.5 EX DG Aspherical"
}, // 2
{ 169, "Sigma 18-50mm f/2.8 Macro"
}, // 3
{ 169, "Sigma 50mm f/1.4 EX DG HSM"
}, // 4
{ 169, "Sigma 85mm f/1.4 EX DG HSM"
}, // 5
{ 169, "Sigma 30mm f/1.4 EX DC HSM"
}, // 6
{ 169, "Sigma 35mm f/1.4 DG HSM"
}, // 7
So the 169 ID is used 8 times, once by Canon (expected), and seven
times by Sigma (wtf were they thinking)...
So I know Exiv2 uses a heuristic to match conflicted lens id's to
names using their focal length's... but it's failing here somehow...
This might be fixable just by moving the 30mm on top of the 15-30mm,
but that would likely just be a workaround...
So you should really file a bug with the Exiv2 project (with the
sample file). I'd appreciate it if you'd communicate the bugs URL back
here, so I can keep an eye on it as well.
