Pearl (6×9 self-erecting)
The name Pearl was given by Konishi and Konishiroku (the later Konica) to many models of rollfilm folders. See also Pearl (4.5×6 folders).
The original Pearl, released in 1909, is for tefuda format plates and 118 film. There is only a brilliant finder perched on the front of the lens. Various lenses and shutters were available for it.[1]
The Pearl 2, released in 1923, is for 6×9cm on 120 film, and was the first Japanese camera sold for roll film only. At first it was supplied with a lens and shutter from Wollensak; alternatives were available later. An improved model, sold from 1930, is made of metal rather than wood, provides for 4.5×6 as well as 6×9 exposures. It has a wire frame finder hinged on the lens assembly, with the eyepiece on the body itself.[2]
The Year-Eight Pearl[3] (1933) is a folder with a self-erecting lens: the bellows open and the lens board springs forward when the front is opened. Focusing moves the entire lens assembly, mounted on a helical. There is a folding frame finder on the body and a brilliant finder on the shutter housing.[4]
This would be the company's last 6×9 folder, and few other Japanese companies would make them.
