Nikon 105mm f/2.5 Ai on D700

I've already had this lens for a few months but still can't believe how incredible sharp it is – not to mention the bokeh. Here's a photo I took last week in a classroom at f/2.5, 1/50, ISO 200, handheld, with just available light (window light). I should probably mention that this image has NOT been sharpened.

Full frame

I'm fairly used to high-IQ lenses (my go-to lenses are the Nikon 14-24mm f/2.8 and the 24-70mm f/2.8 ), but this one is something else.

These are some amazing lenses, and you have a very very fine shot there.

Thank you, sir. This lens made the A Team (the group of lenses that are always in my main bag) in no time. I expect it to stay on that team for a very long time Smile

This lens has a stellar reputation so I'm not surprised. Congrats.

Those out of focus "kids" (Star Wars T-stirt, I'm lookin' at you) need to study harder or they're never gonna graduate! I too love this lens, just shot with it a couple of weekends back.

considering you shot at 1/50 second with a 105mm lens and its that sharp, your hand holding
is pretty good too!

A fluke, believe me Smile

Here's a couple more images, also shot wide open, but this time with a tripod. These two were fully processed (including sharpening).

As a Nikon shooter I might have to get this lens. Do you have picture of the lens?

I personally don't, but you can see it here: http://www.photosynthesis.co.nz/nikon/ai10525b.jpg

The AiS version, which has a built-in hood, can be seen here: http://www.photosynthesis.co.nz/nikon/ais10525.jpg. Other than the hood and the cosmetic difference of the ring, I'm not aware of any difference between the two versions.

I did like this lens a lot , I think one of the best around 100mm lens and luckily so common and inexpensive. I sold only due easy to get another one.

The AI has a longer focus throw - 170deg vs 140deg - not sure if it gains you anything when fine tuning the focus.

They changed the lens formula of this lens over time. There was a recent thread that told the saga. I've tested an early Non-AI, a late Non-AI, an AI, and an AIS. My favorite was the late Non-AI, which was labeled Nikkor-PC as it was an early multicoated version. Only issue is they need to be AI converted to work with Nikon DSLRs. The AI is my second favorite, but I did not like the AIS. I currently only own an AI version...Ray

Very nice handheld shots. I have one I used to use a lot on my FM2 it's in pretty bad shape now. I think mine is a non-ai PC version. Not sure what that means. Anybody knows? I remember this lens is often referred to as the "Afghan Girl" because it's the lens used to take the famous "Afghan Girl" photo from National Geographic. Not sure which version the photographer used though.

I guess this lens shows how the market nowadays differ from back then, and how the digital mirrorless system impact the market. Who would've thought keeping one of the best lenses in the 10xmm focal range back in the days such as this one would break even or make a loss in terms of value now. And on the other hand, a lens such as the Trioplan that's probably considered mediocre in this focal range back then would become a few times more expensive now. Well back then I guess we won't discuss these two lenses on the same page because they are for two different camera systems. But the mirrorless system changes the possibilities and alternatives for us. Well at least for Nikon and Pentax users I guess.

I have this lens (AI version) for a long time and is a very sharp optics. I made a MTF analysis of my Nikkor lenses and this one of the best, even compared with current ones. I haven't the AIS version, but considering results from Nikkor 50mm f/1.8 comparison (NO AI, AI, AIS, series E, AFD) I suspect AIS is the best. Nikkor-Q 135mm f/3.5 is another "monster".

You pretty much have the best one. I sold all mine over time but ended up picking up an AI to keep based on my tests. I didn't want to deal with converting the late-AI version...

I just picked up the 105 member of this pre-K family....the 200 is my last lens from PJ days in the 1960s/70s...the 135/3.5 is the only sib (silver nose but with the long scalloped focusing ring of these three) that I don't have but since I already have TWO 135/2.8 Nikkors...the pre-k Q-C tank and the compact K (AI optics, pre-AI aperture ring)....it's one lens I don't think I need....

The AIS has the same optics as the AI but there are a few differences....
1. The AI came in a two varieties....wide-scalloped metal focusing barrel of the pre-K that came with an AI aperture ring as an option, (see pic above), and the rubber focusing barrel of the "K" that also came in the non-AI or the AI aperture ring option.
2. The focusing rotation of the AI is much longer for a more gradual focusing than the AIS
3. The aperture leaves of the AI is reportedly a bit rounder than the AIS...affecting its bokeh....
I now have both the AI (the pre-K version), and the AIS, so I look forward to comparing them...in particular the bokeh

Where does this information come from ? Do you have a link to a source ? According to http://www.photosynthesis.co.nz/nikon/index.html the Ai lenses were introduced in 1977 after the F, C and K lenses. "Ai-conversion" kits were made available for the earlier lenses but they became "Ai-converted" lenses and not "Ai" lenses. The distinction may seem unimportant but, for example, some people see subtle differences between the image produced by an "Ai converted K" lens and that produced by an Ai lens itself.

Assuming that you mean "Ai converted" which one are you talking about ? The "F-Sonnar", "F-Xenotar" and "C" all predate the "K".

Here are versions of pre-AI lenses and conversions...that I have (owned)....
The 300/4.5-H converted with optional OEM AI aperture ring, and the factory 300/4.5 AI "K" version with the updated aperture ring but not with the updated mount...same optics, different cosmetics..
The 300/4.5 ED was the updated OPTICAL version of this lens...

Neither of these version have the protruding AI post at the rear of the mount...as with the case with the 85 and 135 lenses pictured here....the post came later with the final AI update by Nikon...(see it on the 105AI at the bottom, and missing on the 105 pictured above with the 200/300)



Here's the 85/1.8 lens....the "K" on the left that and "H" on the right...the "K" had been converted with the optional OEM aperture ring to AI though NEITHER were AI optically....the next 85, the F2 version, was AIS



The "cut" conversion of the 200/F4-Q



The post-Q.C 135/2.8....the compact 135/F2.8 AI-optical formula "K" version withOUT an AI aperture ring...it has the multicoating, but is not so designated (the ".C" on the earlier versions of the 135, 105, 85, 50 and others)...
The AI mount with the protruding post (see it in the 105/2.5 AI-K below) and the AIS notched mount came later



The 105/2.5 AI "K" lens, the updated cosmetics of the optically identical P.C I now have...



The 50mm F2-H went through all these cosmetic/mount iterations, but (other than updated coatings) optically it remained the same.

Thanks for your reply. I'm afraid that I still don't understand your terminology.

According to the photosynthesis link given earlier this lens is a simple "Ai". It could be wrong I suppose but ......

Do you mean 50 mm F2-H ?

Oooops....yes I meant the 50/F2-H

Yes your lens is an AI in that it has an AI mount...but....

Again, "K" refers to COSMETICS NOT OPTICS...
In some cases there was an optical upgrade along with the cosmetic upgrade...e.g. the 135/2.8 that was updated cosmetically and optically, BUT NOT AS AN AI MOUNT...though an AI aperture ring was available as an option, as it was for several other pre-AI lenses...the 135/Q.C, 300/4.5-H, etc.....BEFORE the "K" upgrade.
...and....
In some cases there was an "K" cosmetic upgrade with no upgrade to the optics, e.g. the 85/1.8 pictured above and the 105/2.5...

Here's the 105/2.5 that is virtually identical to yours in that it has the "K" upgrade BUT it does NOT HAVE the AI aperture ring...thus preventing it from being used on the latest Nikon dSLRs.

No....I have both the AIS version of the 105 GAUSS optics AND THE PRE-AI version of 105 GAUSS optics...

Simply because the "K" and the "Ai" share the same cosmetics doesn't mean that you can call a "K-lens" an "Ai lens". And you can't do it even when you've replaced the aperture ring of the "K" with a new factory (Nikon) ring.

Please look at the pair of pictures of the 105 mm f/2.5 Ai lens. In the left hand picture you can see a metal post or prong projecting from the mount and just touching the picture frame. You can see the same post at the bottom of the lens in the left-hand corner of the right hand picture. It's called a lens speed indexing post, or more simply, a lug. The diagram here may help. It's needed for matrix metering in some cameras. It's present in "Ai-lenses" but not in "K-lenses". If you visit the photosynthesis site you can find pictures of the "K" and "Ai" lenses and you will see that they are different.

That still allows three possibilities - F, C & K. All are pre-Ai - even the K!
