The lens features a 5-element, 5-group design with 7 straight aperture blades, an aperture range of f/2 to f/22, and a minimum focusing distance of 0.85 meters. It measures approximately 63mm in diameter and 61mm in length, accepts 52mm filters, and weighs 310 grams.
The initial manual-focus version of the lens was introduced for AI-compatible cameras in 1977, while the updated AI-S version, featuring a tweaked focus throw, lighter body construction, and a linear aperture that allows for program/shutter-priority modes on newer cameras, was produced from 1981 to 1995.
AI-S lenses, which stands for "Automatic Indexing Shutter," designed to communicate precise aperture information to the camera body, are distinguished by a small notch cut into the chrome bayonet flange at the rear of the lens; two rows of aperture numbers, with large primary numbers, and a smaller secondary row that can be seen directly from inside the viewfinder; with the smallest aperture number (e.g., f/16 or f/22) painted in orange.

On the Nikon D200, the camera on which the lens was paired for these test shots, the Nikkor Ai-S 85mm f/2 is equivalent to a 127.5mm short telephoto lens on a full-frame camera. The focal length gives you the hedge with a better working distance and stronger background separation, especially useful for portraits, flowers, small product shots, and compression-heavy compositions where you want to simplify the frame.
The Nikon D200, a renowned semi-professional, mid‑range prosumer APS-C digital SLR camera introduced in 2005, is high on the esteem list among vintage digital camera enthusiasts and collectors. The camera, built with a magnesium‑alloy body and extensive weather and dust sealing, is fitted with a 10.2MP CCD sensor famed for delivering incredibly rich, punchy color saturation, and a film-like organic rendering style at lower ISO settings.
