Nikon Nikkor 28mm f/2.8 AIS

Get within eight inches of your subject with a wide lens and watch most of them fall apart at the edges. This one does not. The 28mm f/2.8 AIS focuses to 0.2 meters, closer than almost any other 28 of its era, and it stays corrected the whole way there because Nikon built in floating elements, their Close Range Correction system, CRC. So you can shoot a flower, a hand, a plate of food from a foot away with the near environment still readable behind it, edge to edge, instead of smearing into the corners the way a fixed-group 28 does as you rack it in close. People chasing that look in other systems often ended up buying a second, dedicated lens. With this one it comes standard, and on the cheap body.

Wide open at f/2.8 it is good in the middle and not much else. The center is already sharp, the corners are soft and a touch low in contrast, and there is visible field curvature if you go pixel-hunting on flat brick walls. By f/5.6 the whole frame is sharp and even, and it holds that way out to f/11. Color runs slightly cool with controlled, contrasty rendering and good micro-detail, the look you expect from Nikon glass of the early eighties. Flare control is decent for a multicoated lens of that vintage but not bulletproof. Put a strong sun in the corner and you get a veiling wash, which is why a 52mm screw-in hood such as the HN-2 earns its keep.

The build is the other reason these still sell. All metal, a beautifully damped focus ring, the AIS aperture coupling that meters on everything from an FM2 to an F100. It is small, takes the common 52mm filters that half the Nikon manual lineup shares, and weighs almost nothing in the bag. This is a documentary and street focal length, the moderate wide that takes in a room or a street corner without the distortion drama of a 24, and the close focus quietly doubles it as a detail lens on the same body.

The weakness you have to live with is those corners wide open, plus a bit of barrel distortion that shows up on architecture. If you shoot interiors or repro work where straight lines at the edge matter, the later 28mm f/2.8 AF-D or a dedicated wide will serve you better. Handheld in available light, it never comes up.

Today it trades cheap, often cheaper than the older f/2.8 AI it replaced is worth, and it is the 28 people cross-shop against the Voigtlander Color-Skopar and the older f/3.5 AI. The CRC version is the one to hunt; not every 28mm f/2.8 Nikon made got it, but the AIS did. When you do work it close, remember the metering. At 0.2 meters you are racking the optics forward of infinity, and Zone Light Meter can fold the extension factor into the reading so your close-up exposure is not a fraction of a stop dark. The floating design keeps that loss small, so it is a quiet correction rather than a dramatic one, but it is still the difference between right and slightly under.
