Nikon 300mm f/2.8 History
Manual Focus (links take you to full reviews)
Auto Focus (links take you to full reviews)
1971 - 1976
Nikon's first primitive 300mm f/2.8 ED super tele was impractical because it had klunky, slow traditional unit focusing and a manual diaphragm. As you focused, the entire lens had to rack in and out, not exactly the thing for sports, which is the whole point of this lens.
Because the whole lens had to rack in and out, it has to move a lot to focus closely. To make a reasonably-sized lens, the close focus distance is limited by how much mechanics the maker wants to provide to allow the lens to rack out far enough.
The manual diaphragm means you had to flick a ring to stop down the lens to the taking aperture after focusing each shot. After the shot, you had to flick it the other way to open the diaphragm to focus for the next shot! Preset manual diaphragms went away form most lenses back in the 1960s, but no one had made an automatic diaphragm for a lens this big yet.
Since the whole point of a fast tele is sports and action, the klunky focusing and manual diaphragm defeats the purpose of a 300mm f/2.8. People bought these to shoot at f/2.8, but the focus is still a pain.
These pre-AI lenses won't mount on most modern Nikons. Don't worry, this version was never very popular so it's unlikely you'd come across one for sale.
I will ignore this lens for the rest of this article. It's a non-player and very rare because it was so awful for actual photography that no one bought them.
1977 - 1982
Nikon 300mm f/2.8 ED-IF AI. This was the world's first practical super-speed super-tele, and very popular.
1982 - 1986
Almost identical AI-s version.
1986 - 2005
New version of AI-s. Same optics, but now focuses to 10' (3m) instead of 13' (4m) and has a permanently installed protective front plate instead of a 122mm filter thread. It weighs 3.5 oz. (100g) less than the previous two versions and is 1/2" (14mm) longer than the earlier 2 versions.
1986 - 1988
First AF version, which was the manual focus Nikon 300mm f/2.8 ED-IF with a hole drilled up the side for the screw-type autofocus. AF was so slow that it was one of the reasons sports photographers changed to Canon, and have never had a reason to come back. Whoops! Slow AF is what lost Nikon the pro market. This first AF version is identified by a milled (fine-ribbed) glossy black AF/MF ring. The first AF versions focus as closely as their contemporary manual versions, 10' (3m).
1988 - 1992
AF-n version, still the same optics as the 1977 original and same slow AF as before. This version is identified by the coarse, crinkle-finish ribbing on the AF/MF ring; its ribs have about the same pitch as the focus ring ribs.
1992 - 1996
For the first time since 1986, Nikon put a focus motor into the lens, and for the first time since 1977, Nikon updated the optics. Nikon calls these lenses AF-I, for internal-motor autofocus. The 300mm f/2.8 AF-I focuses more closely than the previous AF versions, down to 8' (2.5m).
The AF-I were the forerunner of AF-S lenses, which use a different kind of motor. The AF-I should work and focus perfectly even on the D40.
Sadly, the Nikon AF-I 300mm f/2.8 was also a slow focuser, confirming to all the pros who moved to Canon that they made the right choice. The good thing about the AF-I version is that it adds extremely helpful focus lock buttons on the front of the lens.
The Nikon 600mm f/4 AF-I, also introduced in 1992, is as slow as the 300mm AF-I. In 1994 Nikon introduced the Nikon 400mm f/2.8 AF-I which has a much better AF-I system and is very fast. (The 300mm AF-I was unchanged.)
1996 - 2001
First AF-S 300mm f/2.8, which finally is the first Nikon 300mm f/2.8 which auto focuses quickly. It has newer optics than the AF-I version. This first AF-s version focuses as closely as the AF-I. It is the heaviest 300mm f/2.8 ever made by Nikon at 3.1 kg. It now takes a 52mm filter in a rear drawer, compared to every previous version which took a 39mm filter in a drawer.
2001 - 2004
AF-S II, which focuses a little more closely: 7.2' (2.2m) vs. 8' (2.5m) for the previous AF-S version. It also weighs less, 2.95 vs 3.1 kg.
2004 - 2009
The Nikon 300mm f/2.8 VR adds vibration reduction for great results hand-held. This version focuses to 7.2' or 2.2m.
It's the same as the old 2004-2009 VR model, adding only an "M/a" autofocus mode.
To quote Nikon: "The lens optics and Nano Crystal Coat so well received with previous lenses have been adopted without modification," meaning this is the same lens.
Nikon also claims an additional stop of VR performance.
1971 - 1986 manual lenses take 122mm screw-in filters.
1977 - 2005 manual lenses take a 39mm filter in a rear drawer. They also came with a gel filter holder that can be used instead of the 39mm holder.
1986 - 1996 AF lenses also take 39mm filters in a rear drawer, and also came with a gel filter holder that can be used instead of the 39mm holder.
1996 - current day (2007) AF lenses take a 52mm filter in a rear drawer.
The manual lenses weigh less than the AF lenses.
The 1977 - 1986 manual lenses weigh 2.5 kg and the 1986 - 2005 manual lens weighs 2.4 kg.
Only the heaviest 1971-1976 pre-AI dinosaur weighs just a tiny bit more (2.6 kg) than the very lightest AF-S II version (2.56 kg).
Both original AF versions weigh 2.7 kg. The original AF-I and AF-S weigh 3.0 kg. The the VR weighs 2.85 kg.

If you're a cheapskate shooting landscapes on a tripod, get an ancient used manual focus version and save some money. That's what I did.
For sports, get an AF-S version, and for hand-held use, get the latest VR version.
Even the first 300mm f/2.8 ED of 1977 is one of the sharpest lenses ever made, and the same has been true for every other Nikon 300mm f/2.8 since then. (I've never seen one of the old non-AI versions.)
I have not shot with many of these, but considering their heritage and the fact that every f/2.8 super telephoto ever made by Nikon (and Canon) has been spectacular (and spectacularly expensive), I see no optical reason to pick one lens over another except for minimum focus distance. The newest versions focus almost twice as closely as the oldest.
These superteles have always been Nikon's forté. Chose among them based on autofocus speed (or not), VR, and close focus distance.
Manual Focus Suggestions
Pass on the ancient 1971 - 1976 , non-AI, manual aperture, not mountable on most modern cameras versions. These are rare because no one bought them back when they were new, so it's unlikely you'll run across one.
Everything from 1977 - 2005 is about the same. All the ED-IF from 1977 - 2005 have the same excellent optics.
The versions from 1986 - 2005 focus more closely, 10' (3m) vs. 13' (4m), have a permanently installed protective filter on front instead of a 122mm filter thread, weigh 3.5 oz (100g) less but are 1/2" (14mm) longer then the earlier versions.
If I had a choice, I'd get the closer focusing (1986 and newer) version, but you take what you can find. I found and bought the 1977 - 1982 version.
For landscapes and portraits, the pre-AF-S versions sell cheaper, so go get one if you can handle slow AF.
For sports and action, pass on any of the original AF and AF-I lenses from 1986 - 1996. They focus much too slowly!
For action and sports, the whole idea behind the 300mm f/2.8, get the AF-S version of 1996 or newer.
I work hand-held, and would prefer of course the newest and current 300mm f/2.8 VR version introduced in 2004, but I'm too cheap to buy one.
