Product Description

The Nikon NIKKOR-H Auto 300mm f/4.5 is a manual focus telephoto prime lens featuring an optical design based on the "H" (Hexa) designation, indicating a construction of six elements arranged in five groups. This formula is optimized to provide sharp, high-contrast imagery over a long 300mm focal length, making it ideal for wildlife, sports, and distant subjects. The lens barrel is constructed from rugged, all-metal materials, reflecting the high-build standards of the vintage NIKKOR line and providing the necessary stability for such a significant telephoto optic.

As a Pre-AI (Pre-Aperture Indexing) lens, this model features the classic "rabbit ears" meter coupling prong, allowing for mechanical exposure integration with period-correct Nikon F and F2 film bodies. The "Auto" designation denotes an automatic diaphragm mechanism that keeps the aperture fully open for bright, accurate viewing and focusing, and stops down to the selected f-stop automatically at the moment of shutter release. Manual aperture settings are controlled via a dedicated ring, which ranges from a maximum of f/4.5 down to f/22.

Designed for both handheld and tripod-mounted use, the lens includes a built-in, sliding metal lens hood that protects the front element from stray light and reduces flare. A key operational feature is the integrated, rotatable tripod collar, which allows the photographer to balance the center of gravity on a tripod head and easily switch between landscape and portrait orientations without detaching the camera. The focus ring is wide and deeply knurled with a long rotation throw for high-precision manual adjustments, while the front of the lens accepts 72mm screw-in filters.
