Nikon 8mm f/2.8 Fisheye-NIKKOR Non AI Nippon Kogaku Japan Manual Focus Lens Review

The Nikon 8mm f/2.8 Fisheye-NIKKOR is a classic manual focus lens from the Nippon Kogaku era, designed to capture a full 180-degree hemisphere as a circular image on film. This Non AI mount lens produces a distinctive 23mm circular image on the frame, making it a specialized tool for ultra-wide experimental photography. Its extreme depth of field eliminates the need for focusing (sharp from 20 inches to infinity at f/2.8), and it includes six built-in filters (Skylight, Medium Yellow, Deep Yellow, Orange, Red, and Light Green) to modify color and contrast without external attachments.

This is a legacy optic that requires compatibility with older Nikon bodies or adapters for modern cameras. The circular fisheye effect is niche, suited for creative projects rather than standard shooting. At over 12 ounces and without a lens hood (due to the extreme field of view), it's a purpose-built lens for photographers seeking a specific aesthetic or archival Nikon glass. The used market pricing reflects its collectibility and rarity.
