The Nikon Series E 36-72mm f/3.5 was introduced in the late 1970s / early 1980s as part of Nikon's lightweight 'Series E' lens lineup, designed to complement compact 35mm SLR bodies like the Nikon EM and FG.
A standout feature of this zoom lens is its constant f/3.5 maximum aperture, ensuring consistent exposure values throughout the focal range. It utilizes a single-touch 'push-pull' zoom and focus ring design for fast handling. Covering moderate wide-angle to portrait focal lengths, it serves as a practical everyday walkaround vintage lens. Built with the native Nikon AI-S mount, it pairs seamlessly with classic film SLRs and converts easily to digital mirrorless systems via simple mechanical adapters.
