Nikon Nikkor 180mm f/2.8 ED AIS

Stop this lens down to f/4 and the background behind your subject melts into a smooth, even wash with clean separation and nothing nervous in the highlights. That rendering is why the 180mm f/2.8 became the working portrait and sideline telephoto for a generation of Nikon shooters. It was never flashy. It just delivered, over and over, which is a rarer thing.

The ED glass is the reason it holds up against faster, pricier teles. Nikon dropped extra-low-dispersion elements into this design specifically to kill the color fringing that plagued fast telephotos of the era, and it works. Even wide open at f/2.8 the center is genuinely sharp, with contrast that survives backlight better than most lenses from the early eighties. Stop to f/4 or f/5.6 and the frame tightens up across most of the image; the extreme corners only fully snap in around f/11. Color is neutral, leaning faintly warm, the classic Nikkor signature that photographs skin without pushing it pink or sallow. The out-of-focus rendering is one of its quiet strengths, smooth and well corrected, no onion rings, no hard outlining on point sources.

People bought it for compression and reach without the bulk of a 300mm. The 180mm f/2.8 was a staple short sports and press tele all through the manual-focus years before autofocus took over. Portrait shooters love the working distance, far enough off the subject to render features without distortion, close enough to still hold a conversation. It also pulls double duty for landscape, isolating a distant ridge or a single tree where that ED-corrected contrast actually shows.

The honest limitation is close focus. There is no CRC or floating-element group in this design, so right down near the minimum distance, wide open, the image goes a little soft and you want f/4 to firm it back up. It is also not an apochromat, so a trace of longitudinal CA lingers on high-contrast edges in fast-aperture shots. Neither is a dealbreaker, but they are real, and anyone telling you this lens is flawless hasn't pushed it close and wide open. The other quibble is sheer mass; it is a dense slug of metal and glass, and a long handheld session lets you know it.

Today it sits firmly in the affordable-classic tier. People cross-shop it against the 105mm f/2.5 and the later AF 180mm f/2.8D, and on bokeh smoothness specifically against the 105mm f/2 DC. It usually wins on value, because the manual-focus AI-S body sells for a fraction of the autofocus version while giving up nothing optically. The 72mm filter thread is common, so polarizers and ND filters are easy and cheap to source. On a tripod for landscape, drop a 3-stop ND on it for a long daylight exposure and let Zone Light Meter fold that filter factor into the reading, so you are not doing the stop math in your head as the light goes. Check the aperture blades for oil before you buy, and you have a lens that will keep working long after the gear-of-the-month crowd has moved on.
