Nikon Nikkor 105mm f/4 Ais

The Nikon Micro-NIKKOR 105mm f/4 Ai-S is a classic manual-focus macro lens produced between 1981 and 1983. It is widely celebrated by enthusiasts for its exceptional sharpness, which some claim was unrivaled in the 105mm Micro-NIKKOR lineup until the arrival of later autofocus versions.
