Thanks Jys, Thanks for your reply.
Below are the two programs and their results for my lens; Exiv2 reports : AF-S DX Nikkor 16-80mm f/2.8-4E ED VR Lensfun file : Nikon AF-S DX Nikkor 16-80mm f/2.8-4E ED VR What I don't get is where the lens ID comes from? From what I've seen it's the lens manufacture but I don't see it as part of the exif data. Surely if the lens maker assigned the number exiv2 and lensfun could call the lens whatever they wanted and it would all work because there is that constant value. I tried the workaround in the first link but this did not resolve the issue. So will try logging the issue with exiv2.
