Nikon 55mm f3.5 Micro-Nikkor Pre-AI Lens

The Nikon 55mm f/3.5 Micro-Nikkor is a manual focus macro prime lens built for Nikon’s F-mount SLR system, representing a pre-AI era Nikkor optic. At 55mm with an f/3.5 maximum aperture, it delivers a short standard to mild telephoto focal length well suited to close-up and macro photography of small subjects including insects, flowers, products, and fine detail work, as well as general photography at standard shooting distances. The Micro-Nikkor designation indicates a lens designed and optimized for close focusing and macro reproduction, and it achieves a maximum magnification of 1:2 without an extension tube, extendable to 1:1 with the addition of the appropriate Nikon extension tube accessory. As a pre-AI lens, it predates Nikon’s AI metering coupling system introduced in 1977, and full metering compatibility on later AI and AI-S bodies may require a physical modification to the aperture ring. Fully manual operation covers both focus and aperture adjustment directly on the lens.
