Nikon 200mm f4 Nikkor-Q Auto Pre-AI Lens

The Nikon 200mm f/4 Nikkor-Q Auto is a manual focus telephoto prime lens built for Nikon’s F-mount SLR system, representing a pre-AI era Nikkor optic. At 200mm with a constant f/4 maximum aperture, it delivers a dedicated telephoto focal length well suited to portraiture, wildlife, sports, and general longer-reach photography. The Q designation refers to the optical formula, indicating a four-element construction within the Nikkor naming convention of the era. 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. Compatible with Nikon F-mount film SLR bodies of the appropriate era, and adaptable to mirrorless systems via F-mount adapters with appropriate consideration of metering compatibility.
