Nikon's original AF constant f/4 telephoto — one of the first AF Nikkors with push-pull zoom.
The Nikon AF Nikkor 70-210mm f/4 is one of Nikon's earliest autofocus telephoto zooms, launched around 1986. The constant f/4 aperture distinguished it from cheaper variable-aperture alternatives. Push-pull zoom mechanism for fast focal length changes.
Optically decent for its era — sharp in the centre with constant f/4 providing consistent exposure. Body-driven screw AF. The push-pull zoom is fast to operate but can develop play over time. ED glass on some versions improves contrast.
Nikon F mount with 62mm filter thread. Approximately 740g. Full-frame coverage. No VR stabilisation. Push-pull zoom. Body-driven AF — requires camera with AF motor. Minimum focus distance 120cm.
Available used very cheaply. The constant f/4 is the enduring appeal — consistent and practical. The AF-S VR versions are dramatically better. Push-pull mechanism can ingest dust and develop looseness. Only for budget users with AF-motor-equipped bodies.
