Nikon Micro-NIKKOR 55mm f/2.8 AI-S – Now, then and always? – By Clifton Dowell

A 30-year-old, hand-me-down Nikon lens recently bit the dust and I decided to replace it. Surprisingly, the exact model I was replacing is still available today. Try doing that with a computer component or a phone charger. But Nikon’s F mount is classic and virtually all the manual focus lenses manufactured by the company today are still AI-S lenses – a standard that first hit the market in the early 1980s. (The exceptions are a few specialty lenses.)
