Before the development of the Konica FR, Konishiroku had released the Konica S 35mm fixed-lens rangefinder camera, and the Konica F 35mm SLR. The Konica F introduced a vertical metal focal-plane shutter, whereas the Konica S provided fully automatic correction of the parallax and field of view with the distance, a feature introduced on the earlier Konica IIIA and called "living finder" (生きているファインダー) at the time.
The Konica FR was an attempt at combining these two features into an interchangeable-lens rangefinder camera. The project was directed by Kurita Yoshikazu (栗田善一), chief of the design department, and the rangefinder, lens mount and lens barrel were designed by Yamada Yutaka (山田豊). The camera was built around the Copal Square I shutter module, the same that was adopted in 1960 on the Konica FS 35mm SLR.
The Konica FR was never announced to the press and never went into full production. Konishiroku seems to have thought that a rangefinder camera such as this could not compete with the increasingly popular SLRs of the time.
Surviving cameras
At least two surviving examples of the FR are known, with serial numbers 123453 and 123455. It seems clear that only the last digit is meaningful, and this indicates that at least five prototypes were made. Both cameras were the property of the Konica company in the early 2000s, and one was exhibited in the JCII Museum in 2005. They are perhaps still owned by Konica Minolta, or have been transferred to Sony.

Konica I Type B
Konica I Type C
Konica I Type Cs
Konica I Type D
Konica I Type E
Konica I Type F
Konica I Type Ab
Introduced in August 1947 The top plate of the camera carries the serial number, the model name (‘Konica’) and the inscription ‘Made in Occupied Japan.’ The leatherette on the back door shows the name ‘Konishiroku’ embossed in ornamental letters, while the leatherette on the bottom is blank. The camera was fitted with collapsible f/3.5 Hexar (four elements in three groups) lens set in a Konirapid shutter with a black face and lettering picked out in silver. The lens has a 26mm outer diameter. The focusing scale is in meters. The price was ¥19,400.
1946/1947 Konishiroku Japan Konica-I (Early type). Hexar f3.5/50mm Lens.
Konica I Type As
Introduced in late 1947. The camera is identical in appearance to the Type Ab, with a Hexar f3.5 lens set in a Konirapid shutter BUT with a silver face with lettering picked out in black (as are all subsequent models). The lens has a 32mm outer diameter.
Konica I Type B
Introduced in March 1948. The top plate of the camera now carries the serial number, the model name (‘Konica’). The leatherette on the back door still shows the name ‘Konishiroku’ embossed in ornamental letters, while the leatherette on the bottom is now embossed with the inscription ‘Made in Occupied Japan.’ The camera was fitted with a Hexar f3.5 lens set in a Konirapid shutter. Part way through the production run of this variant, a Hexar f2.8 version was also made available. Both were sold concurrently. The focusing scale is still in meters. RARE version marked in KATAKANA script.
Konica I Type C
Introduced sometime in 1949. The camera is identical in appearance to Type B, but lacking the name ‘Konishiroku’ embossed the back door. It was fitted with the two Hexar lens options already available for Type B (Hexar 2.8 and 3.5). Tests of the camera were published around 1948 and it was advertised in magazines dated June 1948 through June 1950.
Konica I Type Cs
The camera is identical in appearance to Type C, but from now on the lenses are set in the synchronised Konirapid-S shutter (B, 1–500).
Konica I Type D
Introduced in 1950. The camera is identical in appearance to Type C, except that the text on the camera bottom now reads ‘Made in Japan.’ It would appear that the version with the Hexar f/3.5 was sold concurrently with Type E, which had the Hexanon f/2.8 mounted.
Type E
Konica I Type E
Introduced in August 1950. The camera is similar in appearance to Type D. The main change was the introduction of the Hexanon f/2.8 lens. Units with distances marked in feet were made for the US market. It was advertised in magazines dated August 1950 through January 1951.
Konica I Type F
The camera is identical in appearance and technical details to Type D. The only difference is that ‘Made in Japan’ is now engraved on the metal door lock wheel instead of being embossed in the bottom leatherette.
