    Overview

    The Nikon Micro Nikkor 55mm f/3.5 non-Ai is a vintage manual-focus macro lens known for exceptional sharpness and flat-field performance, making it ideal for product and reproduction photography. Its double-helicoid focusing allows continuous focus from infinity to 1:2, extendable to 1:1 with the PK-3 ring. Build quality is robust, surviving drops. Weaknesses include slow aperture and manual focus, unsuitable for action. It suits photographers seeking an affordable, sharp normal lens for static subjects on mirrorless or manual-focus cameras.
