Lens Overview — Nikon 300mm f/2.8 ED
Key Features — Nikon 300mm f/2.8 ED
300mm f/2.8 Prime: A fixed 300mm focal length with a fast f/2.8 maximum aperture delivers strong subject isolation and usable performance in lower light conditions.
ED Glass Elements: Extra-low Dispersion glass minimizes chromatic aberration, producing sharp, high-contrast images across the frame even at wide apertures.
Nikon F Mount: Compatible with Nikon's extensive F-mount ecosystem, including film and digital bodies, as well as mirrorless systems via adapter.
Full-Frame Coverage: Designed for full-frame image circles, so the 300mm field of view is unaffected by crop factor on full-frame Nikon bodies.
AI-S Manual Focus: The AI-S coupling provides precise aperture control with compatible Nikon bodies, while the manual focus ring offers smooth, tactile control suited to deliberate shooting.
Large-Format Filter Thread: The large front element requires a large-diameter filter thread, accommodating high-quality neutral density, polarizing, and other filter types.

Description — Nikon 300mm f/2.8 ED
The Nikon Nikkor AI-S 300mm f/2.8 is a prime telephoto lens designed for Nikon F-mount cameras with full-frame coverage. Its fixed 300mm focal length and f/2.8 maximum aperture make it a fast, long-reach option for photographers who work in manual focus. There is no autofocus — focusType is Manual only — placing complete control in the photographer's hands.
With no image stabilization, disciplined shooting technique and physical support equipment become especially important at this focal length. The lens weighs 2,900g, a figure that underscores its professional-grade construction and the optical requirements of a fast prime at this range. A 122mm filter thread accommodates large-format filtration.
Compatible with the broad range of Nikon F-mount cameras, this lens offers a consistent, fixed perspective ideal for photographers who value optical simplicity and prefer a manual shooting workflow.
