Nikon Ai-S Nikkor 800mm f/5.6 IF-ED

The Nikon Ai‑S Nikkor 800mm f/5.6 IF-ED was introduced in 1986, offering extreme telephoto reach for specialized wildlife and nature photography. Its Internal Focusing design and ED glass elements provide smooth handling, reduced chromatic aberration, and crisp, high‑contrast images even at long distances. Built as a robust manual‑focus super‑telephoto, this 5.45 kg lens remains a favorite among photographers who demand maximum reach and optical precision.
