Nippon Kogaku's 35mm f/3.5 W-Nikkor, a rangefinder classic in M39 mount

The W-Nikkor 3.5cm f/3.5 comes from the Nippon Kogaku Japan era, before the Nikon name unified everything. Made for the M39 Leica Thread Mount, it pairs with any LTM-native rangefinder body and adapts readily to modern mirrorless cameras with an appropriate screw-mount adapter. The 34mm filter thread is an oddity by today's standards, so tracking down step-up rings or period-correct filters takes a bit of legwork, but that's part of the deal with vintage glass.

At f/3.5, this is a moderate-speed 35mm, not a low-light weapon. What it is, is a piece of optical and mechanical history with the character that comes from that lineage. The fixed 35mm focal length puts you squarely in classic street and documentary territory. The black/chrome finish is period-correct and, on most M39 bodies, looks exactly right. For photographers who treat their shooting tools as objects worth caring about, this lens delivers that in full.

Who It's For

Film photographers shooting M39-native rangefinders like the Leica IIIf or Soviet FED and Zorki bodies get a factory-matched pairing with a lens that was designed for exactly this ecosystem. Digital shooters using Sony E-mount or Fujifilm X-mount mirrorless cameras with M39 adapters gain a 35mm perspective with the rendering character of mid-century optical design. Street and documentary photographers drawn to a compact, unobtrusive profile will find the fixed 35mm focal length forces intentional framing. Collectors and gear historians have a tangible artifact from Nippon Kogaku's pre-Nikon branding period.

Key Features

  • 35mm fixed focal length for street and documentary work
  • f/3.5 moderate aperture, period-appropriate for rangefinder use
  • M39 Leica Thread Mount compatibility with direct LTM bodies
  • 34mm filter thread requiring step-up rings or vintage filters
  • Nippon Kogaku Japan manufacture, pre-unified Nikon branding
  • Black/Chrome finish, original cosmetic design
  • Adapts to modern mirrorless systems with M39-mount adapter

FAQ

Will this lens work on modern cameras?
Yes, with an M39-to-mirrorless adapter. It's a native Leica Thread Mount lens, so it mounts directly to any LTM rangefinder body and adapts readily to modern systems with the right screw-mount adapter.
What's the filter thread size?
34mm, which is uncommon today. You'll need to hunt for step-up rings or period-correct 34mm filters, though adapters exist.
Is f/3.5 fast enough for low light?
No. This is a moderate-speed lens suited to daylight and bright indoor shooting. It's not a low-light performer.
Why does the body say "Nippon Kogaku" instead of "Nikon"?
This lens predates the unified Nikon brand name. Nippon Kogaku Japan was the original manufacturer before rebranding to Nikon.
What's the focal length good for?
35mm is a fixed focal length for classic street and documentary work. It's a constraint, not a limitation, if you shoot that way.
Does the black/chrome finish affect optical performance?
No. The finish is cosmetic and period-correct for vintage rangefinder lenses.
Can I use this on Leica or Kiev rangefinders?
Yes. Any M39 LTM-mount body-Leica, Kiev, or other period-correct rangefinders-accepts this lens directly.
