105/2.5 *PC* coated version. There are 5+ versions of the F mount 105/2.5, but I *think* the *PC* one is the rarest.
Hmmm... I have one of those.
A real jewel...

Very nice, sharp, but not too sharp.
I mostly use the lens in color, wide open with the cat, I can follow the cat around, and easily blur a messy background into a nice studio pastel ...
Of course, the lens is great for people too!
Gee, I Ai'd a bunch my F mounts and they work fine on my D200 in A and M mode which is all I would use anyway. When I want to let it out, I use the excellent CV 40mm/f2 with the "chip".I am not sure what are the 10 most rare but I can say that there certainly are any number of excellent F mount lenses that are great performers - even now. Overall the prices of manual lenses seems to have fallen a bit due to the fact that most DSLRs need a "chipped" lens for all of its functions to work. This applies even more to early non AI lenses which will not mount and function on later cameras. But there are also some desirable rarities that seemed to still be in demand. The 58mm Nokt Nikkor for example and the 300mm f4.5 ED. Both appear to be in great demand and attract a premium. I think I can say that Nikkor lenses are also beautifully made.
There are also many good lenses that are relatively cheap. The 50mm f2.0 is an excellent example being common and a great lens which turns in lovely photos, especially in black and white.
Agree completely! Before the D200, when only the expensive Nikon DSLR's could meter the older lenses, and the prices of them was really low, I managed to finally pick up my "dream set" which I couldn't afford back when they were new (so I went into Pentax).
20/3.5-UD, 24/2.8, 35/2, 85/1.8, 105/2.5, and 180/2.8. All of them are AI-converted with the factory part, except the 85, which was converted by my friend Pete Smith. I've used all of them on my Canon 20D with adaptors, but maybe one day I'll pick up a D3 when it's been replaced and the price comes way down.
Interesting, Nikon returned my 105/2.5 when I sent it for conversion in the 70's, saying they would not convert that one, and doubled the price on the other two lenses I sent.
Have had a couple of them, always a terrific lens.

It depended on the serial number of the lens, some were constructed differently and could not be "factory converted" with a new aperture ring. Typically, the lenses without screws in the rear were not eligible for factory conversion. Other shops would cut a groove in the aperture ring, but not Nikon. Some lenses were more expensive to convert, such as the GN-Nikkor.
I had my 105/2.5 "RIFR", 24/2.8 Nikkor-NC, and 55/3.5 Nikkor-P factory Ai'd for $18.50 each. In the 1970s of course.
I don't understand your "cringing" remark.Having collected the early non-AI F mount Nikkors for years, it makes me cringe hearing about them being converted to AI, especially when the aperture ring is mutilated by grinding. Not to long after the introduction of AI lens indexing, I remember sending off a mint "K" type 85/1.8 to Nikon for conversion. Today, it is very rare finding a true mint "K" type 85/1.8 in original condition.
The 5.5cm/3.5 Micro Preset has already been mentioned as a rarity. The "NKJ" labled 180/2.8 non AI & the "NKJ" labeled 28/2.0 non-AI are two more that are not seen very often. You can also add the "NKJ" labeled, 9 aperture blade, 35/1.4 non-AI to the list of rarities. Another rarity is the 3.5cm/2.8 non-AI "Tick-Mark" lens while the 3.5cm-8.5cm/2.8 non-AI zoom has to rank up there with the UV 55mm/4 as two of the rarest F mount Nikkors.
