Nikon 10.5cm (105mm) f/2.5 Nikkor-P.C Nippon Kogaku Japan Lens for Rangefinder, Black/Chrome {52}

Nippon Kogaku's 105mm f/2.5 Nikkor-P.C for Nikon S-mount rangefinders.

The Nikkor-P.C 10.5cm f/2.5 is one of the defining portrait focal lengths from Nippon Kogaku Japan, built for the Nikon S-mount rangefinder system. Its five-element P.C optical formula was engineered to deliver controlled rendering at f/2.5, a maximum aperture that gives meaningful subject separation at 105mm without the engineering compromises that came with faster glass of the era. The black and chrome finish is period-correct and shows the manufacturing care Nippon Kogaku applied to its professional rangefinder lineup.

Rangefinder coupling means focus confirmation happens through the camera's viewfinder patch than a ground glass, which changes how you work with a portrait-length lens at wider apertures. The 52mm filter thread accepts standard accessories. This is a manual-focus lens built around a mechanical system, and it rewards shooters who already understand the S-mount's operational rhythm. For anyone invested in that system, this focal length and aperture combination represents the kind of glass Nippon Kogaku considered a cornerstone of its professional optical catalog.

Who It's For

Photographers shooting on Nikon S-mount rangefinder bodies will find this lens purpose-built for their system, with rangefinder coupling that integrates directly with the camera's focus mechanism. Portrait and documentary shooters working at 105mm benefit from the f/2.5 maximum aperture, which provides meaningful light-gathering at a classic medium-telephoto distance. Film photographers who prioritize period-correct equipment will appreciate the Nippon Kogaku Japan manufacture and the five-element P.C optical formula. Collectors focused on Nikon's rangefinder era will recognize the black and chrome finish as consistent with the production standards of that system.

FAQ

What optical formula does this lens use?

The Nikkor-P.C uses a five-element P.C optical design, engineered to control rendering at the f/2.5 maximum aperture without the performance trade-offs that faster glass required during this era.

Is this lens rangefinder coupled?

Yes. Focus confirmation happens through the camera's rangefinder patch in the viewfinder rather than a ground glass, which is how S-mount rangefinder lenses operate.

What filter size does the 105mm f/2.5 accept?

The lens has a 52mm filter thread for standard screw-in accessories.

Which Nikon cameras are compatible with this lens?

The Nikkor-P.C mounts to Nikon S-mount rangefinder bodies. You'll need an S-mount rangefinder camera to use this lens.

Is this a manual-focus lens?

Yes. The Nikkor-P.C is fully manual focus with mechanical rangefinder coupling - there is no autofocus.

What's the difference between the P.C formula and other Nikkor designs?

The P.C is a five-element design optimized for portrait work at f/2.5. Nippon Kogaku engineered this formula to deliver controlled subject separation without the optical compromises that came with faster apertures in rangefinder glass of the period.
