Nikon 24mm f/2.8 NIKKOR-N Auto Non-AI Manual Focus Lens Review

The Nikon 24mm f/2.8 NIKKOR-N Auto is a Non-AI manual focus lens from Nikon's classic film era. With a 52mm filter thread, this wide-angle prime was produced by Nippon Kogaku, Nikon's original corporate name, before the AI (Automatic Indexing) aperture system was introduced in 1977. As a Non-AI lens, it will not mount safely on many modern Nikon DSLRs without modification or an AI conversion, limiting its compatibility primarily to older film bodies, AI-converted cameras, or adapted use on mirrorless platforms.

This particular unit is listed in bargain condition from KEH, meaning it shows significant cosmetic wear and may have optical or mechanical issues that affect image quality or operation. At $85, it offers an affordable entry point for shooters seeking vintage character or experimenting with legacy glass, but buyers should expect cosmetic blemishes and possibly degraded performance. The 24mm focal length provides a classic wide-angle field of view useful for environmental shots, architecture, and street photography, though the f/2.8 maximum aperture is modest by modern standards.
