Thank you for the sample image. The LensModel tag is hardcoded in the image file:

nkbj@bohrium:~$ strings IMG_2159.jpg | grep +LSC
EF50mm f/2.5 Compact Macro +LSC
EF50mm f/2.5 Compact Macro +LSC

Third-party lens makers sometimes masquerade their lenses as similar OEM lenses. This is such a case.

I closed this bug report since this is not a bug.
