Lens Overview — Nikon 800mm f/8 ED IF
Key Features — Nikon 800mm f/8 ED IF
800mm Prime Focal Length: A fixed 800mm focal length delivers extreme reach for wildlife, birding, and distant sports subjects that cannot be physically approached.
Extra-Low Dispersion Glass: ED (Extra-low Dispersion) elements reduce chromatic aberration, which is especially important at long focal lengths where color fringing is harder to control.
Internal Focus Design: IF (Internal Focus) means the lens does not change length during focusing, keeping the balance stable on a tripod and preventing front element rotation.
Full-Frame Coverage: Designed to cover the full 35mm image circle, this lens produces no vignetting on full-frame Nikon DSLR bodies.
Nikon F Mount: The Nikon F mount offers broad compatibility across decades of Nikon DSLR bodies, and with an adapter, can also be used on many mirrorless systems.
Manual Focus Only: There is no autofocus motor; focusing is entirely manual, requiring patience and technique but giving the photographer precise control over the focus point.

Description — Nikon 800mm f/8 ED IF
The Nikon Nikkor AI-S 800mm f/8 is a prime super-telephoto lens mounted on the Nikon F system, purpose-built for photographers targeting subjects at extreme distances. Its full-frame coverage means it works without compromise on Nikon's full-frame DSLR bodies, and its single focal length of 800mm makes it a highly specialized but potent tool for disciplines like wildlife and birding photography where reach is everything. Focus is manual only — there is no autofocus mechanism — so composing and locking onto a subject demands technique and patience.
With a maximum aperture of f/8 and no image stabilization, solid support is not optional but essential. The lens carries a weight of 4,500g, which underscores the need for a capable tripod or monopod in the field. A 122mm filter thread is available for those requiring filtration.
This is a deliberate, specialist lens for photographers who know exactly what 800mm manual focus shooting demands.
