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. The only finder is a small mirror device 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, provided for 4.5×6 as well as 4.5×9, and also has a wire frame finder.[2]
The Year-Eight Pearl[3] 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. The finder consists of two metal frames that spring up from the top of the camera (in addition to the small mirror finder on the front of the lens).[4]
