Ideal Uses

Fantastic as a general-purpose wide-angle lens for manual-focus cameras.

Also works as a high-performance lens on all digital cameras, especially FX, but must be focussed manually.

 

Not for

I'd skip it for AF and digital cameras, since the 16-35mm VR zoom is more practical, but much larger and more expensive.

Introduction

I use these stores. I can't vouch for ads below.

This is Nikon's sharpest manual-focus wide angle lens.

Nikon let their designers go wild on this one. Instead of a simple 5 element design that every other 28mm f/2.8 lens uses, including the original AF version, this lens has EIGHT elements in EIGHT groups. This allows it a level of correction seen in no other Nikon wide angle.

No other Nikon 28mm lens performs this well: the 28mm f/1.4D AF has some barrel distortion and really is optimized for night photography, and every other 28mm lens just isn't designed as thoroughly.

This AI-s lens (1981-present) is completely different from the older AI lens. Nikon made a big upgrade to the optics when they upgraded it to AI-s, and they really pulled out all the stops.

Not only does this Nikkor uses 8 elements, it also uses floating elements to optimize its performance as it is focused at every distance.

This is also Nikon's closest-focusing lens, with a close-focus distance of 7 inches (0.6 ft), or 20 cm.

There is no sharper manual-focus wide angle lens made by Nikon, and it is the only Nikon wide angle, along with the 15mm f/3.5, that is completely free from barrel distortion at ordinary distances.

Optically this is an almost perfect lens, and one of the most perfect lenses you can get to fit a Nikon camera.

 

Compatibility       intro     top

The manual-focus 28mm f/2.8 AI-s works great with most Nikon cameras, film and digital.

It works flawlessly with every manual focus Nikon ever made, from the F of 1959 through the FM3a and today's FM-10.

On the D3X, D3, D700, D300, D200, D2 and F6, use the "Non-CPU Lens Data" menu option to set 28mm and f/2.8 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.

It works perfectly on every professional film camera (F, F2, F3, F4, F5, F6), and adds Matrix metering on the FA, F4 and F6.

The meters of cheaper digital (D90, D5000 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.

 

History and Comparisons

1950s

Nikon made 28mm f/3.5 for its S-series rangefinder cameras. It's not very good, but it is tiny.

 

1960-1983

Nikon made 28mm f/3.5 F, AI and AI-s lenses in several iterations.

 

1974-1981

Nikon made the 28mm f/2.8 AI, which had 7 elements in 7 groups.

It lacks CRC and focuses to only 1 foot, and is also a great lens.

 

1979-1995

Nikon made an optically inferior 5-element 28mm f/2.8 lens that was sold as the Series E, and also as the first two iterations of non-D AF lenses.

 

1981-today

Today's AI-s lens came out in 1981, and has been sold unchanged ever since, even as optically inferior autofocus versions came and went.

 

1994-today

Nikon redesigned the crummy 5-element 28mm f/2.8 design, used for the Series E through the AF version, into a 6 element 28mm f/2.8 AF-D version. Its performance is still much poorer than this 8-element manual-focus AI-s lens.

Performance

Performance is just about perfect. Read accordingly.

 

Coma

There is some very slight coma in the corner at f/2.8 that is gone by f/4, far better performance than any other wide angle Nikkor wide open save the 28mm f/1.4D AF.

 

Falloff (darkened corners)          performance     top

I've exaggerated this by shooting a gray field and placing these on a gray background.

Sharpness      performance     top

Sharpness is extraordinary.

The 28mm f/2.8 AI-s is diffraction limited by f/5.6. That's lens designer speak for "really, really good!"

 

As shot on the 24 MP Nikon D3X:

It's simply stunning. Even at 24MP, it's brilliantly sharp and contrasty even at f/2.8, and doesn't get any better as stopped down.

It's so good that it's diffraction-limited at f/5.6, meaning that it's slightly less sharp at f/8.

The sides are just as sharp.

The last few millimeters of the corners are less sharp due to some mild coma at f/2.8. They improve as stopped down.

 

As shot on Velvia

f/2.8: sharp all over with the exception of very slight coma in the corners, and some light falloff.

f/4: Fantastic, seems diffraction limited!

f/5.6: Ditto. I've never seen a sharper lens on my Nikon.

 

Speed, Actual      performance     top

It seems to be a bit slower than f/2.8, probably closer to about f/3.0. That's not a big deal; cheating a bit like that allows Nikon to squeeze in a little more sharpness.

 

Recommendations

This is the sharpest manual-focus wide angle made by Nikon. Even Nikon's newest and best 16-35mm f/4 VR zoom isn't any sharper, except maybe in the last few millimeters of the corner, and it distorts.

If you want great sharpness and perfectly straight straight lines, go get one of these lenses new or second hand. You'll love it.

This lens is fantastic on manual-focus cameras, however on digital FX cameras I prefer the convenience of the extraordinary 16-35mm f/4 VR zoom.

You can still buy this 28mm f/2.8 brand-new at B&H Photo Video in 2010, or of course used over eBay.

On some cheaper AF cameras you lose metering, but heck, mounted on your F6, F4 or FA you even get matrix metering.
