    Overview

    The Nikon Nikkor 300mm f/4.5 ED IF Ai is a compact, lightweight manual-focus telephoto praised for sharpness and contrast even wide open. Its ED glass minimizes chromatic aberration, though some color fringing may appear in extreme contrast. Build quality is excellent with smooth focusing and a built-in hood. Weaknesses include light falloff characteristics and softness in infrared. It suits photographers who value portability and manual control, especially for sports or adventure.
