The Nikon Nikkor AI-S 300mm f/4.5 ED IF Lens is a high-performance telephoto lens designed for Nikon F-mount cameras. It features Extra-low Dispersion (ED) glass elements to minimize chromatic aberrations and an Internal Focusing (IF) system for smooth and fast focusing. This lens is ideal for capturing wildlife, sports, and distant subjects with exceptional clarity.

Minimizes chromatic aberrations for superior image quality and color accuracy.

Extra-low Dispersion (ED) Glass

Enables faster and smoother focusing without changing the lens length.

Internal Focusing (IF) System

Offers portability and ease of use for outdoor photography.

Compact and Lightweight Design

The Nikon Nikkor AI-S 300mm f/4.5 is a **prime** telephoto lens built for the **Nikon F mount**, with full coverage of a **full frame** sensor. Its fixed **300mm** focal length places it squarely in telephoto range, offering a dedicated single-focal-length solution rather than the flexibility of a zoom. The maximum aperture of **f/4.5** provides adequate light transmission for a lens of this class. Focusing is entirely **manual** — there is no autofocus mechanism — meaning the photographer takes full control over focus accuracy and speed. **No image stabilization** is present, so sharp imagery at this focal length depends on solid technique or the use of a support system. The **72mm** filter thread is a practical choice, aligning with a widely available filter ecosystem. At **745g**, the lens is a manageable carry for a telephoto prime of this reach. Compatible bodies must use the **Nikon F** mount system.

Fixed 300mm focal length provides dedicated reach for wildlife, sports, and distant subject photography without the optical compromises of a zoom design.

300mm Telephoto Prime

Extra-low Dispersion glass reduces chromatic aberration, delivering sharper, higher-contrast images at the edges of the frame.

ED Glass Element

Focusing is achieved internally, so the overall lens length does not change during focus — useful for maintaining balance on a tripod.

Internal Focus Design

Offers reasonable light-gathering capability for a manual telephoto prime, supporting subject separation and usable shutter speeds in good light.

f/4.5 Maximum Aperture

Compatible with a wide range of Nikon F-mount film and digital SLR bodies spanning several decades, including full frame DSLRs.

Nikon F Mount

Image circle covers full frame sensors, making it fully usable on bodies like the Nikon D800, D810, and D3 series without vignetting.

Full Frame Coverage

Smooth, damped manual focus ring is designed for precise and repeatable focus control, characteristic of Nikon's AI-S mechanical standard.

AI-S Manual Focus

Standard 72mm front thread makes it straightforward to source compatible filters such as polarisers, ND, and UV filters.

72mm Filter Thread

At 745g, the lens is relatively manageable for a 300mm telephoto, though tripod or monopod support is recommended for sharp results at this focal length.
