Open a bug report if a lens name in exiv2 doesn't match the LensFun name. > PS: In the lensfun slr-tamron.xml file, I found my 28-75mm lens > just profiled for crop 1.0.

If the 1.0 calibration was done carefully, it can be used for smaller crops, too -- unless they are really small. It is nicer to have two LensFun entries, one for 1.5 and one for 1.0. LensFun actually contains such doubletts. However, it doesn't seem to be able to handle them. At least UFRaw, Darktable, and Rawstudio doesn't work, so I think it is a bug in LensFun.
