Nikon 2.8cm (28mm) f/3.5 NIKKOR-H Non AI Nippon Kogaku Manual Focus Lens {52}

Nippon Kogaku-era 28mm f/3.5 NIKKOR-H, Non-AI F-mount classic.

The NIKKOR-H 28mm f/3.5 comes from the Nippon Kogaku period of Nikon's history, carrying the original branding that predates the company's later identity. Non-AI coupling means this lens works through manual aperture control, putting exposure decisions entirely in the photographer's hands. The 52mm filter thread is a standard size that makes finding glass filters straightforward.

At 28mm and f/3.5, this is a moderate wide-angle lens suited to deliberate, considered shooting. Manual focus demands you engage with the scene than react to it, which suits photographers who already work at a measured pace. For anyone building or rounding out a collection of Nikon F-mount glass from this era, the NIKKOR-H represents the optical and mechanical craftsmanship Nippon Kogaku was producing at the time.

Who It's For

Film photographers shooting Nikon bodies from the Non-AI era get native compatibility and full manual operation without any adaptation. Collectors focused on Nippon Kogaku-branded glass will find this 28mm a period-correct piece with the NIKKOR-H designation intact. Street and documentary photographers who prefer a wide-angle focal length and manual aperture control will appreciate the deliberate pace this lens enforces. Anyone already invested in 52mm filters across a vintage Nikon kit can slot this lens in without acquiring new filter sizes.

FAQ

What does Non-AI mean on this NIKKOR-H lens?

Non-AI refers to the manual aperture coupling design that predates Nikon's later metering integration systems. You set aperture manually on the lens barrel and control exposure directly without any mechanical linkage to a camera body's metering system.

Will this 28mm lens work on modern Nikon F-mount cameras?

Mechanically, the Nikon F mount accepts this lens on any F-mount camera body. Metering and automation features depend on your specific camera model and its compatibility with pre-AI glass - check your camera's manual for details on stop-down metering or manual exposure modes.

What's the filter size for the 28mm NIKKOR-H?

52mm. That's a common thread size, so finding replacement filters or adding accessories like polarizers is straightforward.

Is f/3.5 fast enough for a 28mm wide-angle lens?

f/3.5 at 28mm is moderate aperture. It's sufficient for daylight and bright conditions, but you'll need faster film or higher ISO if you're shooting in overcast or indoor light, or if you want shallow depth of field. Manual focus also lets you control focus precisely at any aperture.

What era is this Nikon NIKKOR-H lens from?

This is from the Nippon Kogaku period of manufacture, before Nikon later changed branding. The NIKKOR-H designation and manual-only aperture control place it in the film-era mechanical lens lineage that defined Nikon's early reputation for build quality.

Does this lens have autofocus?

No. The NIKKOR-H is fully manual focus. You focus by turning the focus ring, which suits deliberate shooting and works on any Nikon F-mount body.
