I only have two "vintage" Nikkors, both 105's: An AI'd copy of the last Sonnar 105/2.5 P, and the relatively rare Bellows-mount 105/4. Neither are multi-coated, and do suffer from flare issues, but are very simple designs, so contrast is still good, and I just make sure to use a hood. Neither lens is essential to me as I have more modern, multi-coated alternatives, but they have a distinct look, and are certainly beautiful mechanical jewels.
Extending the concept of "old Nikon glass" to include AF-D lenses (which so many folk seem to disparage as being outdated designs, superseded by much better new technology in the latest glass), I have a nice little collection of these so-called "flawed" lenses. I love my 28/1.4D, which has turned my venerable 24/2 into a shelf-queen. I also enjoy my 18/2.8D which has a very poor reputation (many consider it the worst of all 18mm Nikkors), but suits my purposes. It is very compact (despite it's 77mm filter-size), and sure it vignettes pretty horribly wide-open, but it gives me access to a super-wide without having to carry one of the bulky super-wide-zooms. It was an expensive lens when new, but I got a great price on it, less than for any of the MF versions, so I'm happy, and have just learned not to avoid f/2.8 for the most part. Finally, I have the 105/2 DC, which is perhaps the most quirky of my AF-D lenses with its Defocus feature. I'm not convinced it will replace my MF 105mm lenses, but it has a distinct and lovely rendering, particularly wide-open portraits.
