Nikon Nikkor 105mm ƒ/2.5 – Lens Review

Nikon Nikkor 105 F 2.5 Lens Review 1

We’re back with another noteworthy lens, and this one’s a real legend for Nikon photographers of a certain age. Yes, if you were shooting film during the 1960s or in any of the subsequent three decades, you’ll likely have heard of this lens, owned this lens, loved this lens, or coveted this lens. It’s Nikon’s Nikkor 105mm ƒ/2.5, and it’s one of the best mid-telephoto and portrait lenses in the world.

Sound hyperbolic? I don’t blame you for thinking so. But it’s the truth. This is a lens that found a home in nearly every professional Nikon photographer’s bag for close to fifty years. Steve McCurry used it to shoot what is arguably one of the most recognizable images of the 20th century. His shot, Afghan Girl, was famously featured as the cover image on the June 1985 issue of National Geographic Magazine. 

That’s right. This lens is pretty much famous.

So let’s take a closer look. What is it about this lens that makes photographers gaze longingly through the mists of time? Why is it so spectacular? And how is it suited to today’s era of mirror-less cameras and DSLRs?

I’ll spare our good readers the rather boring story of how I managed to find this lens in the musty basement of a New England saltbox. I’ll skip the part where an ancient, craggy man told me of his outlandish, 1960s era adventures with a Nikon F SLR, and the way he almost forcibly demanded that I buy the Nikkor in question. And I think I should also pass over the part where I purchased the lens for a single dollar bill.

Instead, let’s just get to the review.

Build quality is simply stunning. Many old-timey shooters cite the 105/2.5 as the lens that finally gave Nikkor a reputation for making world-class lenses, and when holding it in the hand it’s tough to argue otherwise. From the milled mount to the glorious chunk of glass that is the front element, every part of the lens has been designed and built to an impeccable standard. We don’t want to keep yammering on about it, so just trust us. In all of its various iterations, the 105/2.5 is a gorgeous piece of work.

But what do we mean by “various iterations”? Well, in its 40-plus years of continued production the 105/2.5 saw quite a few revisions. That might throw some would-be owners into a tailspin of uncertainty and confusion. Don’t let it. Every version of the 105/2.5 makes amazing images, there are just a handful of small, specific differences that may determine which version you choose to buy.


To start, let’s talk about compatibility of Pre-AI, AI and AIs lenses with various camera setups. If you’re unsure of the fundamental differences between Pre-AI, AI, and AIs lenses, a little reading will help.

The condensed version goes something like this: Nikon’s F mount has been in continuous production since it was introduced with the original F in 1959. As camera technology changed and improved, rather than scrap the F mount and start over with an entirely new mount, Nikon continually updated its F mount. While newer F mount lenses worked best with newer F mount cameras, the retention of the basic mount meant there would always be backward and forward compatibility (with some minor caveats). To illustrate the point, just last year we were able to easily use a Nikkor lens from 1980 on one of the newest Nikon DSLRs, the D610. That’s pretty unique in the world of photography, and it’s super-nice of Nikon to respect their customers and their legacy in our current era of toss-away tech.

As it pertains to the 105/2.5 the compatibility question surrounding Pre-AI, AI, and AIs lenses isn’t as scary as it might at first seem. The 105/2.5 was offered in all three configurations, so with minimal thought we can quickly suss out which lens is right for your application.

If you’re shooting a Nikon DSLR or a Nikon film SLR made after 1977 it’s best to hunt for an AI or AIs version, as this will allow full functionality with your machine. If you’re shooting a Nikon SLR made prior to 1977 you can include Pre-AI versions in your search. These older models tend to be less expensive, which is helpful to those on a budget, and in the case of this particular lens, they’re just as capable as their newer descendants.

Compatibility issues melt away instantly when shooting today’s crop of mirror-less cameras. Mounted via an adapter to a mirror-less camera, all these lenses will be functionally indistinguishable. If you’re one of the many mirror-less lovers who can’t get enough of legacy glass (and we don’t blame you), simply find the model you like best at the best available price, mount it, and shoot.

This Nikkor 105/2.5 is of the pre-AI variety, but the mount has been converted to work on all Nikon MF cameras.

More than just mount compatibility, there were myriad other changes implemented throughout the lifecycle of the 105/2.5. The most notable of these occurred in the 1970s, when the lens underwent its first and only optical redesign.

This began with the implementation of multi-coating. On older style lenses this was designated by the letter “C” following “Nikkor-P”. Later AI and AIs lenses would drop the indicator, as advanced Nikkor coatings had become standard across the range. This change helped improve color balance, reduced flares and ghosting, and quelled chromatic aberration.

The next big change came when the lens’ optical formula switched from a Sonnar-type consisting of five elements in three groups, to a Xenotar-type consisting of five elements in four groups. This helped correct a number of undesirable optical aberrations including spherical aberration and coma.

We’d understand if some of our readers assumed, given these last few paragraphs, that the Pre-AI version is to be avoided. On paper, it would appear that way. But it’s just not the case. While the 105/2.5 was indeed improved over time, we’d like to make it clear that the older version is in no way sub-standard. Yes, even with its older optical formula stemming from the pre-NISC era, the original 105/2.5 is among the best mid-telephotos in the world. Is it better than the AI and AIs versions? No, but it’s quite possibly better than anything else on offer.

But why is it so amazing? To be blunt, because it feels incredible and makes gorgeous images.

Usability is excellent. The lens is perfectly balanced on a mirror-less camera or vintage film machine alike. In both Pre-AI and AIs versions, it’s weighty without being heavy (though later versions are heavier). Nikon managed to keep things exceptionally compact. When focused to infinity it’s nearly as snub-nosed as certain 50mm lenses we’ve used.

Manual focus lenses need to feel truly fantastic when you spin that ring, and the 105 does not disappoint. Its focus throw is long and smooth, with the scalloped aluminum focus ring of the Pre-AI version being especially delightful to the touch. The rubberized focus ring of later models is perfectly acceptable as well, and some shooters will surely prefer it over the metal version (especially in cold climates). Focus distance is indicated in feet and meters, with minimum focus resolving at 3.5 feet. A focus scale is also included, allowing zone focusing when the situation demands.

The aperture ring controls six blades in the earlier version, seven in the later version, from ƒ/2.5 down to ƒ/22 (ƒ/32 in some models). All versions click with the mechanical crispness that so many lenses strive for, yet fail to achieve. There’s a delightful precision to the actuation as the aperture ring slots into its detents. These solid clicks serve as a constant reminder that we’re shooting one of the finest lenses of the film era.

And while the stellar touch and exceptional build quality are great, it’d all be for naught if the lens made crummy pictures. Thankfully the Nikkor 105mm ƒ/2.5’s reputation is well-deserved. This is the kind of lens that makes effortlessly dreamy images every time the shutter’s released.

It’s difficult to decide what makes this lens so incredible. It’s sharper than a Ginsu knife, can isolate subjects better than a supermax prison guard, and renders colors more beautifully than… than something that makes beautiful colors…  I’ve run out of metaphors. It makes gorgeous colors.

Surely it’s the combination of all of these superlatives that make the lens so legendary for vintage shooters. When we find a lens that offers exceptional bokeh, sharpness, color, and contrast, all in a gorgeous physical package, that’s when the magic happens.

Shooting wide open let’s in enough light for relatively easy low-light shooting. While it’s not the fastest aperture in the world, ƒ/2.5 is certainly quite good for a lens of this focal length. Natural and available light portraiture is no problem, and trying out some Golden Hour shots with a backlit subject are a must for any owner of this Nikkor.

Sharpness is exceptional, even shot wide open, though the corners of the frame do naturally fall off a bit. This is to be expected, and the later model 105/2.5s will resolve a bit better in the corners. Shooting at ƒ/4 through ƒ/8 yields shots that are as sharp as any we’ve seen from a vintage lens, with softness likely being the result of imprecise manual focusing rather than a fault of the lens.

With a full-frame camera, details come through in unbelievable clarity and depth-of-field falls away in an organic, gradual way that’s impossible to replicate with lesser lenses on smaller sensors.

Subject isolation for portraiture is fantastic. Headshots are particularly well-done, and shooting wide open creates some really respectable bokeh. While the quality of the blur is a subjective assessment, we think you’ll agree; this lens makes some dreamy blobs of blur. When stopped down the highlights can get a little too hexagonal with the Pre-AI version, so it’s difficult to call it perfect. Later models help keep those balls a bit more round.

Color rendition is just amazing. The lens creates stunning colors with exceptional tonality right out of the camera. Play around a bit in post-processing and there’s no limit to the beautifully saturated images that a good photographer can make with this lens.

In normal shooting situations the lens will not produce double-lines, flares, or ghosts. It just won’t happen. Nikon built a retractable lens hood into the later versions of the 105/2.5. Earlier models used a snap-on or screw-on lens hood. That said, you won’t need it. In order to produce a flare we needed to point the lens directly into the sun and fire away. Even then, the flares were well-handled.

The lens can show a proclivity for light fall-off (vignetting) when shot wide open. Stop it down and it resolves by ƒ/5.6. For those who need to shoot wide open without light fall-off, try using the lens on a digital camera and correcting in post-processing. Doing so is easy and quick.

For film users, the only way to mitigate the vignetting is to stop the aperture down a bit. If these film shooters are looking for subject isolation but can’t stand the vignetting, fear not; shooting at ƒ/4 and even ƒ/5.6 still yields remarkably shallow depth-of-field with close-up subjects.

Another option is to use the vignetting to your advantage. Frame a subject in the center of the shot and allow the fall-off to direct the viewer’s eye.

And if we’re searching for another issue, we can find one with the Pre-AI version when we really scrutinize it against the newer lenses. While we stand by our claim that the Pre-AI version is a phenomenal lens, there’s no denying that the newer versions do a better job at controlling chromatic aberration (color-fringing). With Pre-AI models, shooting high contrast situations can certainly result in purple nonsense at the points of contrast.

Chromatic aberration is visible in the water.

But that’s about it for worries. Aside from these small issues, shooting the Nikkor 105mm ƒ/2.5 is nothing but pure pleasure. It’s a well-designed, well-made bit of glass that countless professional shooters relied upon for years. Back then, it earned its place in the annals of Nikon lore, and as the shooters of today rediscover the joys of legacy lenses and manual focus, it seems the 105/2.5 may have yet another chance to impress.

It’s a lens from which I expected little. An odd focal length, a not-so-fast aperture, and a $1.00 price tag. On the insistence of a stranger, I gave it a shot. After just a few sessions, it’s clear that I’ll never part with it. If that doesn’t tell you all you need to know, I’m not sure what will.

    After sold my old Nikon film gear 15 years ago I came to a point
    were I didn´t take any private pictures any more.
    No idea how to explain – the digital workflow at work was nothing
    I wanted to continue in my free time.
    That changed of of the sudden while running into a cheap offer at Ebay
    were I bought a Nikon F4 for almost nothing.
    First I remembered was I didn´t want any autofocus lens for that and so
    I was looking for some of these old-fasioned Nikkor AI glas.
    Second “accident” happened while winning a auction with some Nikon FE
    and some AI`d Nikkors build in 1959 (Nikkor Q 3,5/135 and Nikkor H 2,0/50).
    Never touched anything that compared to this amazing craftmanship !
    Next hunt was on for the legendary Nikkor 2,5/105 and now I own
    the first Nikkor P 2,5/105 Sonnar type and Nikkor P 2,5/105 Gauss type too.
    The Gauss type offers a much better grip and seems to handle easier to focus
    in situations were you have to be fast or miss the picture.
    What to say – it´s a joy to take pictures with this sort of glass and the way
    of rendering is just outstanding !
    I prefer them over any autofocus lens Nikon build after that period.

    If you ever have the chance to test a Nikkor AIs 2,0/135 at a Nikon FX camera
    just try and be sure you hide your wallet – for me it´s the best of the best portrait
    lens Nikon ever build and a joy to use it on location or street shots !

        Thank you James,
        I am not the opinion that better gear makes better pictures
        but catching a image is also catching a memorie
        and your equipment and the joy to use it is always a part of it.

    Thanks for the review of this outstanding lens. My dad gave me his AI-S version in 1999 when I switched from the old Canon FD system to Nikon. Although I love my other Nikkor lenses, this is my favorite. I believe it can compete favorably with much more expensive lenses from the likes of Leitz, Zeiss, etc. I use it not only for portraits but for landscapes as well. It does color in a way that is natural but not clinical. it has its own indescribable “look.” This my forever lens.

    I just want to add that this lens also does not have excessive contrast, which helps a lot with our sometimes harsh New Mexico light.

    In the mid 90’s I needed a new SLR and bought a Nikon FM2n with 50mm Series E lens at a camera show. Someone encouraged me to buy a 105mm f2.5 AI lens from the same dealer, which I did. For some reason I never used it. I recently dug it out and shot a couple of test rolls with it. I can’t believe I neglected it so long, it really is a fantastic lens. I can’t get over how sharp it is. It’s great for portraits but I’ve also been using it to shoot stone carvings on buildings that are too high up to shoot with 35 or 50mm lens. I’ve started taking it to baseball games. One great thing about using this lens on FM2n is the FM2n’s maximum shutter speed of 1/4000 means you shoot wide open even with 400 ASA film. I’m looking forward to shooting a lot more with it in the future.

    Ah, the Nikkor 105. Sweet lens! Another trip down memory lane. Back in the film days when I walked to school in the snow and bought candy for a nickel, we didn’t use zooms for some reason. The standard PJ gear was the 105/2.5 paired with the 180/2.8, another awesome lens.
