Nikon 55mm f/3.5
Nikon 55mm f/3.5 AI (FX, DX and 35mm coverage, 52mm flters, 8.5 oz./241g, about $50 used). enlarge. I got this one at this direct link to it at eBay (see How to Win at eBay). The current models you can get new are the 55mm f/2.8 AI-s, 60mm AF-D and 60mm AF-S. It helps me keep adding this site when you get anything from those or these links, regardless of the country in which you live. Thanks! Ken.
Ideal Uses: Super-sharp normal lens for manual-focus and FX cameras in good light. Photography of fish in tanks. Nikon's least expensive used macro lens; and it will work on even the cheapest cameras like the D40 but you will have to guess at exposure.
Not for: For serious macro use, 105mm or 200mm lenses are much better ideas because they give you enough room between you and your subject. As a manual focus lens, I wouldn't use this for sports, kids or action since it's too hard to track focus by hand.

Nikon uses the word "Micro" to mean the same thing as "macro." I'll use these words interchangeably.
The Nikon Micro-NIKKOR 55mm f/3.5 is an excellent manual-focus lens. It works perfectly on every manual-focus Nikon camera, and also works great on all better digital Nikons, especially the D3X, D700 and other FX cameras. It won't meter with the cheaper DX digital or AF cameras like the D90; for these cameras, guess and use the LCD, or use the Gossen Digisix meter and hot-shoe adapter.
For manual focus cameras, the newer f/2.8 AI-s version is still made today, and used f/2.8 versions cost very little more. This f/3.5 is a great lens, but if I had my choice, I'd get the f/2.8. I only bought this one to archive here; I already have two f/2.8 AI-s 55mm lenses I bought new over the years.
Even for manual focus cameras today, I'd suggest getting the 60mm AFD since it also will work perfectly on your AF cameras.
The optics of all of these lenses are superlative; it's the mechanics and ease of use with AF and digital cameras which varies.

The manual-focus 55mm f/3.5 AI works great with most Nikon cameras, film and digital.
On the D3X, D3, D700, D300, D200, D2 and F6, use the "Non-CPU Lens Data" menu option to set 55mm and f/3.5 to get full matrix metering, EXIF data and finder read-out of set aperture. It works great in aperture-preferred as well as manual modes on these cameras.
The meters of cheaper digital (D80 and below) and cheaper film cameras (N80 and below) will not couple (or work at all) with this lens, so you'll be on your own guessing exposure using the rear LCD or an external meter, or get a tiny Gossen Digisix meter and hot shoe adapter to meter manually.
See Nikon Lens Compatibility for details on your camera. Read down the "AI, AI-s" column for this lens.
The earliest non-AI versions should be upgraded to AI, otherwise, they are compatible with much fewer cameras. If you have a non-AI lens, see Nikon Lens Compatibility and read down the "pre-AI" column.
Nikon made this same optical design starting in 1961, and changed the cosmetics, mechanics and coatings as time progressed.
The version shown above is the newest AI version made from about 1975 - 1979.
Nikon first made the 55mm f/3.5 Micro for its rangefinder cameras.
God only knows how you focused or composed without through-the-lens viewing.
Nikon didn't make a lot of these; LEICA was the market leader in those days.
THey made at least two different cosmetic versions of this SLR lens.
Nikon made about 100,000 of these early verisons.
THese versions are best iditfied by serial number, or more casually, by a rubber (not fluted aluminum) focus grip.
Nikon made about 500,000 of these later verisons; about 275,000 AI and 165,000 non-AI.
1979 - today
Nikon introduced the improved 55mm f/2.8 AI-s Micro-Nikkor which replaced this f/3.5 version.
This current f/2.8 version adds CRC, close-range-correction, for optimum performance at every distance.
Nikon has made about 600,000 of these — so far.
55mm f/2.8 AF, Nikon's first AF micro, used the same optics as the AI-s verison.
Nikon only made about 50,000 of these.
Nikon made about 150,000 of these non-D AF versions.
Nikon made about 300,000 of the AF-D versions, or about 450,000 total 60mm f/2.8 AF — so far.
The newest version is the 60mm AF-S Micro, which replaces the 60mm AF-D Micro. The AF-S micro will not work on cameras older than about 1993, while all these other lenses are perfectly compatible with them.

Nikon calls this the Nikon Micro-NIKKOR AI 55mm f/3.5.

You also can use the CP-1 plastic bubble, or CP-2 with a PK ring.

The 55mm f/3.5 is a great lens. It just works, and always delivers sharp images.
Manual focus is easy.
Focus is as smooth as silk, perfectly damped with no play.
Lesser digital cameras, like the D300 and down, usually have just one "OK" focus dot, which is not as precise as two arrows and a dot.
The Nikon 55mm f/3.5 has no visible distortion.
For scientific use, plug 0.20 into Photoshop CS2's lens distortion filter for shots made at infinity on film or FX.
Falloff on FX is negligible.
I've exaggerated this by shooting a gray field and placing these on a gray background.
There are no visible lateral color fringes on the D3, which would correct them if the lens had any.

With those caveats, the 55mm f/3.5 Micro-NIKKOR is super-sharp. It makes newer zooms like the awful 24-120mm VR look as bad as they are.

Usage back to top
It's easy, just focus and shoot.
If you need to get closer than 9-1/2," use the PK-13 extension tube to get to 1:1 (life-size at the sensor or film).
Exposure Compensation for external light meters
Focus scale at close focus, Nikon 55/3.5. enlarge.
When focused closer, the lens extends away from the film or sensor. Since the mechanical diaphragm doesn't open to compensate, less light makes it to the film or sensor.
All modern Nikon cameras have their light meters built-in, so they automatically correct and use a slightly longer exposure time.
If you're using a hand-held meter (or non-TTL flash), here is the additional exposure needed as you get closer.
If you do this often, it's much handier to write these factors on a piece of removable white label attached to the focus ring. This way you can read the factor right off the lens as you focus. I simply put dots to mark how many third-stops are needed at the right spots on the front of the focus ring.
R = Reproduction Ratio.
Exposure Factor = (1 + R)2
Stops Compensation: Log2 (Exposure Factor)
Recommendations back to top
The f/2.8 manual-focus 55mm lens is a tiny bit sharper in the corners wide-open at infinity, as are the other f/2.8 55mm and 60mm lenses. Then again, for $65 used, you can't do much better at any price for a lens better than this f/3.5. Stopped down to f/5.6 or f/8, nothing is sharper. Even at f/3.5, the resolving power in the center far exceeds the D3X; just peer through a Lens Scope Converter and you'll see far more detail than you will in a D3X file.
I prefer a 105mm lens or longer for my macro work to allow enough distance for my lighting, or to put little bugs at ease. Friends use this focal length for photographing fish in aquarium tanks. The short focal length allows one to get close to the glass and still be able to see a complete fish, unlike a 105mm.
If you want a macro for duplicating documents then this is a good choice. If you want to photograph little animals, then go instead for a 105mm macro.
The 55mm Micro works great in place of a faster normal lens. When I was younger and stupider I thought that it would not be very good when used at ordinary distances. Whoops, it's spectacular at all distances. Unless you need the extra stop or two offered by the other 50mm normal lenses, you can forget about needing a separate normal 50mm lens if you have this.
