Released in the early 1960s, the Nikon 35mm f2.8 Pre-AI was one of Nikon’s first wide-angle lenses built for their revolutionary F-mount system. Compact and mechanically precise, this early Nippon Kogaku version embodies the charm of the analog era with its single-coated glass, scalloped metal controls, and smooth, expressive rendering. I use this lens on my Nikon F to create photographs that lean into mood and presence rather than technical perfection.

Nikon 35mm f2.8 Pre-AI Lens Profile
General Information
Lens Name: Nikkor-S 35mm f/2.8
Mount Type: Nikon F-mount (Pre-AI)
Serial Number: [insert yours if you’d like it documented]
Production Era: 1962–early 1970s
Made in: Japan
Lens Coupling: Non-AI with “rabbit ears” for meter coupling (compatible with Nikon F Photomic finders)
Optical Specifications
Focal Length: 35mm
Maximum Aperture: f/2.8
Minimum Aperture: f/22
Optical Construction: 7 elements in 5 groups
Minimum Focus Distance: 0.3 meters (1 foot)
Angle of View: 63° (on 35mm/full-frame film)
Filter Thread Size: 52mm
Diaphragm Blades: 6 (rounded)
Coating Type
This lens is single-coated, using Nikon’s early anti-reflective process common in all Nikkor lenses of the 1960s. Reflections under light often appear blue, purple, or amber. While flare resistance is limited compared to multicoated optics, the lower contrast and smooth tonal rendering give the lens its unique appeal—particularly well-suited for expressive black-and-white photography. These coatings contribute to the soft atmospheric look that many modern digital lenses lack.
Physical Specifications
Dimensions: Approx. 63mm diameter × 47mm length
Weight: Approx. 240g
Build Quality: All-metal construction with engraved markings; scalloped metal focus and aperture rings. “Nippon Kogaku” branding confirms early production before Nikon simplified their lens markings
Compatibility Notes
Camera Compatibility:
– Fully compatible with Nikon F and other pre-AI Nikon bodies
– Designed for full-aperture metering on Photomic prisms via rabbit-ear coupling
– Not AI-converted—do not mount directly on AI or AI-S bodies to avoid damaging the indexing tab
Optical Performance Overview
Wide Open (f/2.8): Moderate softness, some vignetting; classic rendering with open shadows and delicate highlights
Stopped Down (f/5.6–f/11): Good sharpness and contrast; excellent across the frame for its age
Distortion: Very low for a 35mm wide-angle lens of this era
Flare Resistance: Modest—best used with a lens hood or thoughtful composition
Rendering: Produces a timeless, vintage aesthetic with soft contrast and smooth tonality; perfect for storytelling, documentary work, or moody black-and-white photography

Collector & Usage Notes
The Nikkor-S 35mm f/2.8 is among Nikon’s earliest wide-angle designs for the F-mount system. The “S” designation refers to its 7-element construction. The inclusion of the Nippon Kogaku name and scalloped controls makes this an especially collectible variant. While not as sharp or contrasty as modern lenses, it offers a unique, atmospheric look ideal for photographers who embrace the creative imperfections of classic glass.
Pre-AI Nikon SLR Bodies (Fully Compatible with Non-AI Lenses)
The Nikon F was the first in a legendary line of Nikon SLRs using the F-mount, and it helped define 35mm SLR photography. Before the AI (Automatic Indexing) system was introduced in 1977, Nikon produced several pre-AI cameras. These models rely on the “rabbit ears” aperture coupling system, and lenses like your Nikkor 24mm f/2.8 (Pre-AI) were designed to work with them.
1. Nikon F (1959–1973)
- The original SLR that started it all
- Modular design with interchangeable prisms and focus screens
- No built-in meter—requires Photomic finders (e.g., FT, FTn) for metering
- Full compatibility with non-AI lenses using rabbit ears
2. Nikon F2 (1971–1980)
- Successor to the Nikon F with improved shutter, ergonomics, and build
- Also modular with interchangeable viewfinders and backs
- Uses Photomic finders like DP-1 (F2 Photomic) and DP-11, which support rabbit-ear coupling
- Some late F2 versions (with DP-12/AS finder) support AI lenses as well, but remain compatible with pre-AI glass
3. Nikkormat FT (1965–1967)
- Budget-friendly companion to the Nikon F
- Built-in match-needle metering
- Manual exposure
- Uses pre-AI rabbit-ear lenses only
4. Nikkormat FTN (1967–1975)
- Improved version of the FT with better metering
- Supports full aperture metering with rabbit-ear lenses
5. Nikkormat FT2 (1975–1977)
- Last Nikkormat before AI transition
- Still pre-AI, uses rabbit ears
- Built-in hot shoe, better ergonomics
6. Nikkormat EL (1972–1976)
- Early aperture-priority auto exposure
- Uses a hybrid mechanical/electronic shutter
- Compatible with pre-AI lenses with rabbit ears
- Slightly more sensitive to mounting pressure—care needed when attaching heavy lenses
AI-Only or Partially Compatible Models (Use With Caution)
- Nikon FM, FE, FM2, FE2, F3, etc. – These AI-era cameras can physically mount non-AI lenses but will not meter, and on some models, may damage the AI tab unless it’s retractable (F3, for example).
- Nikon EL2 (1977) – One of the first AI-only models
- Nikon F2A/F2AS – These use AI Photomic finders (DP-11, DP-12); non-AI lenses will mount, but won’t meter
