Nikon AF Micro-Nikkor 105mm f/2.8D

Cross-shop this against the Tamron 90mm SP Macro and the real difference is reach, not magic. People assume the longer 105mm buys a lot more standoff for close work, but at 1:1 the two are nearly even: working distance lands within a hair of each other, somewhere around 13 to 14cm, so the reach advantage does not really materialize at life size. Where the extra focal length actually shows up is at portrait distances, where 105mm puts noticeably more space between you and a subject's face than 90mm does. Some shooters find the Tamron a touch warmer; both render skin honestly, and the choice usually comes down to which mount you already own and what you can find cheap.

Optically this is one of Nikon's best F-mount macros, but you have to stop down a hair to get there. At f/2.8 it is usable but a little soft and low in contrast, then it snaps to crisp by f/4 and holds across the frame because of the Close-Range Correction system: floating elements shift as you focus in, so the lens stays corrected at 1:1 instead of softening the way fixed-group designs do near minimum distance. Stop to f/5.6 or f/8 and resolution and contrast are about as high as the format gives you. Flare is a known soft spot, with veiling and artifacts when a bright source sits in the frame, though the deep built-in hood tames stray light from outside it. The out-of-focus rendering behind a head-and-shoulders portrait is clean and unfussy, and the seven-blade diaphragm turns highlights slightly polygonal once you stop down, which nobody shooting bugs or product is going to notice.

It pulls double duty as a portrait lens, and plenty of Nikon shooters bought it for exactly that. 105mm on full frame, f/2.8, CRC sharpness once you stop down a touch, neutral skin tones. It is unforgiving of bad skin because it resolves every pore, so it rewards soft light and a steady subject. For macro it is the genre standard: flowers, insects, jewelry, copy work, anything that needs 1:1 with honest color.

The honest weakness is the autofocus. This is a screwdriver D lens, so the body drives it through a slot, and in the macro range it hunts and crawls through the whole focus throw before it locks. Almost everyone working at true close range turns AF off and racks it manually, rocking the camera back and forth to nail focus. It is loud, it is slow, and on a consumer body without an AF motor it does not autofocus at all. The later AF-S VR version fixed the speed and added stabilization, which is part of why the D sells for less today.

The price is what makes it worth a look. The 2.8D trades for a fraction of the AF-S, and if you are manual-focusing for macro anyway, the AF speed barely matters; optically the two are very close. One thing macro shooters run into: as you rack toward 1:1, the extension steals light and your effective aperture drops well past f/2.8, so an in-camera reading made at the marked f-stop underexposes. Zone Light Meter computes the bellows (extension) factor for the magnification you are working at, so the exposure you set matches the light actually hitting the film instead of the number engraved on the ring. The 52mm filter thread also takes cheap, common glass, handy when you are stacking a polarizer to kill specular glare off wet petals.
