You can download a lens correction profile for the Nikon 85mm 1.4 AF-D via the Adobe Lens Profile Downloader tool, which is a free tool that you can find on the Adobe Labs website. Keep in mind that you can also adjust the amount of vignetting correction to taste in LR, whether for specific image or as a default for a given lens if you always want some degree of vignetting. Also, there is both lens vignetting correction, as well as creative vignetting that you can apply to an image that's been cropped, which could lead to asymmetrical vignetting if you weren't careful. When I want some light fall-off for creative uses, I generally use the post-crop vignetting function found under the Effects portion of the Develop module. The Highlight Priority option usually works the best for me.
