First, some history. Nikon introduced their 1.2/55mm lens in December 1965 as a replacement for their 5.8cm f/1.4 lens. The original Nikkor-S version of the 55/1.2 had a simple (though not single) lens coating. It obviously used the pre-AI mount.
In October 1972, Nikon upgraded the coatings and renamed the lens "Nikkor-S.C" (the "C" was for "coating"). The lens I got was built near January 1974, making it only a few years younger than I am.
The Nikkor-S.C version continued until April 1976, when the 55/1.2 was again refreshed. The new version, labeled simply "Nikkor," received a knurled rubber focusing ring and (in July 1977) the new AI lens mount. This final version lasted until April 1978, when the 55/1.2 was retired in favor of the much-improved Nikkor 50mm f/1.2 lens.
So what do I think after a couple months of playing with this baby?
First off, it's soft. You'd expect low resolution wide open at f/1.2. After all, you don't buy an f/1.2 lens because it's tack sharp; you buy it because it can see in the dark and give razor-thin depth of field. The lens gets noticeably sharper at f/1.4, but even there, it's still softer than my Nikkor-S NKJ 50/1.4 lens, which is five years older than this 55/1.2. By the time you stop the S.C down to f/2, it's finally on par with the NKJ at f/1.4. You have to stop the S.C down to f/5.6 (4.5 stops down) before it's finally giving my wide open Pentax Super-Takumar 50/1.4 a run for its money -- and the Super-Tak is seven years older than the S.C. (Takumars had a good reputation for a reason.) Resolution on the S.C 55/1.2 peaks at f/8, and stays good through its smallest aperture of f/16. At all apertures, sharpness drops off a little toward the corners (on a 1.6x crop sensor), but not as far as you might expect. It's a relatively consistent lens corner to corner. Below are links to full-frame test images at each full stop of aperture, plus one test shot from my Super-Tak wide open at f/1.4.
But as I stated earlier, sharpness isn't why you buy this lens. The depth of field really is fun to play with. The additional half stop beyond f/1.4 is noticeable. Focusing accurately at f/1.2 can be a challenge (do not underestimate the gravity of that statement), but once you nail it, you can get some pretty cool portraits with the selective focus that f/1.2 provides.
Here's a few more examples of the depth of field. Note how much tighter it is at f/1.2 than at f/2.8. Even f/2.8 is considered fast by today's zoom standards.
The bokeh is nice and creamy, but out of focus highlights tend to have a sharp, bright ring around them. Compare these two back-lit photos of rose bushes taken at f/1.2 and f/8.
There's no noticeable chromatic aberration, even with the sun or lights shining into the lens. That speaks well of the the new coatings that this Nikkor-S.C lens received.
As "fast 50" lenses go, this thing is a behemoth, dwarfing the other normal primes in my collection. The diameter of the aperture and front glass kind of require that, I suppose. It still manages to utilize Nikon's standard 52mm filter threads, thankfully. While it's heavier than most 50's, it is still a 55mm prime, and as such is still lighter at 410g than any decent quality zoom lens (but not my plastic Canon 28-80mm kit lens, of course). By comparison, my Super-Tak 50/1.4 weighs only 230g. Canon's modern 50/1.2 (Nikon doesn't make an AF version) tips the scales at 545g.
Ergonomically, the lens is easy to focus, with the focusing ring sweeping about 190 degrees from minimum to infinity. The front lens barrel extends about 3/16" (4mm) through that range. Despite its age, the focus ring on my copy turns very smoothly, with just the right amount of resistance.
The aperture ring, which is hidden back by the camera body behind the larger diameter main lens barrel, is still easier to access than most lenses thanks to its scalloped grip that runs the full diameter of the ring. I wish more lenses were made like that! (I'm looking at you, Pentax & Yashica.) That ring has detents at f/1.2, f/1.4, and (like most Nikkors) every full stop thereafter up to f/16.
Canon 7D, which has a 1.6x crop sensor. Some lenses have trouble with mirror clearance on full-frame Canon bodies, but this 55/1.2 clears just fine according to the official list. You can mount it using any standard Nikon-to-EOS lens adapters.
The copy of the lens that I used had a tiny bit of fungus somewhere in the rear elements. It's worth noting here that the rear element groups were serviced as a single unit, not individually. If you find a need to tear open this lens for repair, that could be significant.
Remember that I tested this lens on extended loan from a friend. Would I buy one myself? Certainly not for the $300-400 that they fetch on eBay. I only paid $40 for my Super-Tak 50/1.4, and it spanks this 55/1.2 in both sharpness and convenience. There's no way I'd pay an additional $300 for a half stop of aperture with worse image quality. Then again, simply owning an f/1.2 lens will probably win you the respect and admiration of some of your photographer friends, so if that's your goal, this lens may be a decent option -- especially if you've got a Nikon body. If you have the flexibility that a Canon EOS, Four Thirds, or mirrorless body affords, I'm told you can get better results from either the Minolta Rokkor-X 58/1.2 or the Canon FL 55/1.2 lenses than you'll get with this Nikkor-S.C 55/1.2. The Canon sells for about $100 less; the Minolta for $100 more.

This post is part of my "old glass" series, wherein I elaborate on the various manual focus lenses that I've grown to love. You can read an introduction to the subject in an earlier post. Previously, I've covered the SMC & Super-Takumar 50/1.4 mentioned above, my Tamron 90/2.5 macro, and my Yashica 75-150/4 zoom.

It's always tricky to judge on a lens when you only have the chance to use ONE pre-owned copy. My Nikkor-SC 1.2/55 is a pretty good lens and perfectly usable from f/2.0 in. Wide open it produces that special "lightness" that I want in a superfast lens.ReplyDelete
Thanks for sharing! That's very true. However, several of the reports of this lens that I read online reported sub-par sharpness until you reached the smaller apertures, so I know I'm not the only one. There was definitely some variation in image quality from one copy to another. I tried to represent the most common opinion here.Delete
I have this lens, planning to use it on my 5D classic. I have an adapter with af-confirm chip but I am not able to move it from f1.2ReplyDelete
even dismounted, rotating the ring of the apertures it does not move from wide open.
I am pretty sure I am missing something stupid....
can you give me a tip?
I see two possible problems. Solving either requires you to disassemble the lens.Delete
It could be that your aperture blades are very oily, to the point where they're stuck in the open position. You can read another PRI article to learn how to clean the blades on a Micro-Nikkor 55/2.8 lens, which should be similar.
There's a spring inside that constantly tries to pull the aperture shut (toward smaller apertures / bigger numbers). The aperture dial limits how far the aperture can close.
The little lever on the back of the mount pushes against that spring to open the aperture up when focusing. On a Nikon body, when the shutter is tripped, that lever is released, and the aperture closes down while the photo is made.
If this spring is broken or disconnected, there will be nothing to close down the aperture regardless of what position the ring is in. You're going to have to disassemble the lens and see what's wrong with that spring. If you're lucky, it's just disconnected. If you're unlucky, it's broken. If you're very unlucky, it's missing.
In the latter two cases, I'd recommend checking with a hobby store to see if they know where you can find a replacement spring of approximately the correct size. Since you'll be using the lens manually, it's not the end of the world if it's not quite the right size, as long as it does the job and doesn't get in the way of other mechanisms.
Good luck! Please report back once you've figured out what the problem is.
thank you very much, I will!Delete
