Nikon's flexible walk-around zoom — the manual-focus Ai-S Zoom-Nikkor 28-85mm f/3.5-4.5, with close focus.
The Ai-S Zoom-Nikkor 28-85mm f/3.5-4.5 is a wide-to-short-telephoto standard zoom for the Nikon F system, introduced in the mid-1980s to the Ai-S standard. Its range from a useful wide to a short portrait tele made it a flexible walk-around lens, and it included a close-focus (macro) setting for near work.
This is a manual-focus Nikon F lens with a variable maximum aperture of f/3.5-4.5 across a 28-85mm zoom range, built to the Ai-S standard for full body compatibility. It operates with normal reflex viewing and includes a close-focus setting. Only the verified focal range, aperture and mount are stated; construction details are omitted to avoid error.
This zoom covers wide, standard and short-telephoto framing in one lens, with a close-focus mode for flowers and detail shots. Rendering is respectable across the range for a variable-aperture zoom of its era, with good sharpness stopped down. It suits travel, general use, street and landscape where versatility is the priority.
On the used market the 28-85mm is common and affordable, a practical single-lens option for film and mirrorless. Inspect the elements for haze and fungus, check coatings, confirm the aperture blades are dry, and test the zoom and focus for smooth action, watching for zoom creep in older samples. It adapts to mirrorless as a flexible manual walk-around zoom.
