The Nikon 85mm f/1.8 AIs is a manual-focus short telephoto prime in Nikon's F-mount AIs line, sitting between the 50mm standard and 105mm portrait focal lengths. With its fast f/1.8 aperture it was designed for available-light portraiture, indoor sport and stage work on Nikon's manual-focus SLR bodies of the late film era.

At UK auction in today's market the 85mm f/1.8 AIs is a thinly traded lens, with the single hammer result on file fetching £90 in November 2025 — a wholesale saleroom level rather than a retail asking price. On that limited evidence a clean copy is worth around the £90 mark, though dealer-shop pricing typically sits well above what the lens sells for at auction, and condition swings the figure either way.
