Nikon AF Nikkor 28mm f/2.8D

Nikon built this one to be the wide every amateur could afford and every working photographer could toss in a bag without a second thought. When the autofocus F-mount lineup matured in the early 1990s, the system needed a 28mm at that price point, and the AF Nikkor 28mm f/2.8D, arriving in 1994 as the D-chip update to the older AF version, was exactly it. Not the f/2.8 AI-S that manual-focus people still chase, and not the later expensive primes. This was the plastic-barreled, 52mm-thread wide that shipped alongside a million N90s and F100s.

Optically it is a six-element, six-group retrofocus design, all spherical glass with no special close-focus correction, which tells you the priority was cheap and light, not exotic. It behaves like a competent lens rather than a special one. Wide open at f/2.8 the center is already sharp, the corners are soft and a little smeary, and there is visible falloff. Stop down to f/5.6 or f/8 and it tightens up across the frame, which is where most people who buy a 28mm actually live. Distortion is mild barrel, nothing you cannot ignore for street and reportage. Contrast is moderate. Color is classic Nikkor, leaning neither warm nor cool, which makes it easy to mix with the rest of your kit.

Where it gives ground is flare and field curvature. Shoot into a streetlight at night and you will see veiling and a couple of ghosts; the coating here is Nikon's Super Integrated Coating, competent but not the later Nano Crystal Coat. The field is not flat, so flat-subject work like a copy stand or architecture reveals soft edges before the center gives up. As for bokeh, do not expect much. A 28mm at f/2.8 does not throw a lot out of focus anyway, and what little background blur it produces can get nervous against busy foliage. Nobody buys this for separation.

People buy it for what 28mm has always been for. It is the documentary and street focal length, wide enough to put you in the scene without the distortion theatrics of a 24mm, tight enough that you are not including the whole sky by accident. Loaded on a film body with Tri-X or HP5, stopped to f/8, zone-focused, it gets out of the way and lets you work.

Today it trades cheap on the used market, often under a hundred dollars in clean shape, and it cross-shops against the older f/2.8 AI-S (more metal, more character, manual only) and the third-party Tamron and Sigma 28s of the same era. The reason to pick the D version is simple. It autofocuses, it reports distance to the body for matrix metering and flash, and it weighs almost nothing.

One metering note. Because it is fast enough that you will use it indoors and at dusk, meter it wide open at f/2.8 in low light and let Zone Light Meter place your shadows. The corners go soft there but the center holds, so expose for the part of the frame that matters. The 52mm front takes the cheapest, most common filters Nikon ever made, which is its own quiet argument for keeping one around.
