Fujifilm Fujinon 100mm f/2

Fujinon 100mm f/2

The Fujinon 100mm f/2 is a rare Fuji Photo Film telephoto documented in a rangefinder-coupled Leica thread mount. An early example from about 1963 combines a black-and-chrome barrel, feet distance scale and fast f/2 maximum aperture.

Optical qualities

Rendering

The combination of a 100mm focal length and f/2 maximum aperture provides strong subject separation and a narrow angle of view. Exact factory documentation for the optical formula has not been located, so element and group counts are intentionally left blank rather than inferred from similar lenses.

Handling

The lens focuses through a coupled LTM mechanism on compatible screw-mount rangefinder bodies. Verified figures for minimum focus, filter size, dimensions, weight and diaphragm construction remain unavailable in the consulted primary listing and are therefore not entered.

History

Development and Launch

A documented early black-and-chrome Leica M39 version dates to about 1963. It represents Fuji Photo Film’s specialist rangefinder production at the end of the classic screw-mount era.

Production Evolution

Known examples appear with cosmetic and distance-scale differences. The documented auction example uses a feet scale, but this detail does not establish a separate optical profile.

Special Editions/Variants

Black-and-chrome construction is confirmed for the early lens. Additional finish or scale variants should be recorded only when supported by clear factory or surviving-example evidence.

Collector Notes

Original LTM construction and functional rangefinder coupling are key identification points. Internal corrosion has been reported in surviving examples, making careful optical inspection important.
