This is a work in progress.
Konishiroku (predecessor of Konica) made three standard lenses in Leica screw mount in the 1950s. In the 1990s, before the introduction of the Hexar RF, Konica made other lenses for the same mount: see Konica lenses in Leica screw mount.
Contents
Commercially produced lenses
Announced in 1954
In October 1954, Konishiroku exhibited various products that were under development in three department stores in Tokyo; among them were four different lenses in Leica screw mount.[1] These included two Hexanon standard lenses: a 60mm f/1.2 and a 50mm f/1.9.[2] The following year, the company released a range of three standard lenses: first a 50mm f/3.5 Hexar in collapsible mount, from Spring,[3] then the two Hexanon, from December.[4]
Hexar 50mm f/3.5, collapsible
The Hexar 50mm f/3.5 lens has a Tessar-like formula, of four elements in three groups. The same lens was mounted on the Konica I and IIB at the same period. The version in Leica screw mount normally has a all-chrome collapsible barrel, obviously inspired by the Leitz Elmar 5cm f/3.5. The aperture scale is on the side of the front part, graduated from 3.5 to 22, and the diaphragm is positioned behind the second lens element.
To be continued.
Experimental lenses
To be done.
Other lenses
Hexar 50mm f/3.5 enlarging lens, modified for the Chiyoca
The Hexar 50mm f/3.5 found on the viewfinder-only Chiyoca model was not an official product of Konishiroku but a modified enlarging lens: the maker of the Chiyoca obtained various Hexar enlarging lenses and mounted them on a focusing helix they made themselves.[5] Some sources say that the resulting lens has a rigid barrel,[6] but a polished chrome tube is visible immediately to the front of the focusing ring, perhaps indicating that it is at least slightly collapsible. The aperture ring is that of the original enlarging lens, with a scale on the side from 3.5 to 16. The focusing scale is engraved in feet, and there are depth-of-field indications for all apertures. The finish is all chrome. Lens numbers are known in the 32xxx to 35xxx range; given the unofficial nature of the product, these should not be continuous.
List of lenses
- 35mm f/2.5 Hexanon (six elements in five groups), rigid, all chrome, focusing tab (experimental only)[7]
- 50mm f/3.5 Hexar (four elements in three groups), collapsible, all chrome, focusing tab
- 50mm f/3.5 Hexar (four elements in three groups), all chrome, modified enlarging lens, on the viewfinder-only Chiyoca
- 50mm f/3.5 Hexanon, collapsible, all chrome, focusing tab (on the Ichicon-35)
- 50mm f/1.9 Hexanon (six elements in five groups), all chrome, focusing tab, ¥23,500
- 50mm f/1.8 Hexanon, black and chrome (experimental only, for the Konica FR)[8]
- 50mm f/1.5 Hexanon (seven elements in five groups), all chrome, focusing tab (experimental only)[7]
- 60mm f/1.2 Hexanon (seven elements in six groups), black and chrome, ¥78,000
- 75mm f/3.5 Hexanonsource needed
- 135mm f/3.5 Hexanon, black and chrome (experimental only)[7]
- 15cm f/4.5 Hexar Ser.1, pictured in this page at mflenses.com, all chrome barrel, perhaps for Leica screw mount
- 40cm f5.6 Tele-Hexar (Note: lens uses a 39mm LTM, but it is unknown if it were intended for use on rangefinder cameras or on other cameras using that mount.)
Among these, several of the standard lenses were notably mounted on the Honor, Ichicon-35, Chiyoca and Chiyotax.
