Adobe Camera Raw does not have a lens profile for the Nikon 105mm f/2.8 AF D Micro lens (the discontinued 105 mm - there is a profile for the new Nikon AF-S VR 105mm f/2.8 G IE-F). However, when lens corrections are enabled, ACR (and thus Lightroom too) selects the Sigma Macro 105mm f2.8 ex dg, Nikon Corporation - presumably the Nikon Corporation means this Sigma lens with a Nikon mount. This seems like a minor bug in ACR.
Is there a place to request Adobe create a profile for the Nikon 105mm f/2.8 AF D. There are a lot of these older lenses out there and it is a great lens.
There are indeed a lot of older (and still great) lenses out there, but unfortunately we can't build profiles for them all. This is one reason (a big reason) why we've provided the free Adobe Lens Profile Creator (ALPC) tool, so users can built their own (and share them, too). You can also check the free Adobe Lens Profile Downloader (ALPD) tool and see if other users have already built a profile for this lens.
