Y.K. Optical
Y.K. Optical was a small company based in Yokohama (Japan). It used the brand names Kobalux and Avenon for two wide-angle lenses: Kobalux seems to have been the predominant name in north America, and Avenon the only name within Japan. The lenses were also available under other names, such as Pasoptik,[1] Bower and Adorama, perhaps also Avenar.[2] The existence of a "Komura" name variant is probably a false rumour.[3]
There was a Kobalux Wide 28/3.5 and a Kobalux Super Wide 21/2.8, both in chrome or black finish. They were mainly sold in Leica screw mount, but it is also reported that they existed in Leica M mount. The Cameraquest page tells us that the 21/2.8 existed in at least three variants. The two lenses were sold together with an external finder (also available separately).
Production stopped in February 2002.[4]
