Pearlette

This is a work in progress.

The Pearlette (パーレット) is a Japanese folding camera taking 4×6.5cm and 3×4cm exposures on 127 film, made by Konishiroku (predecessor of Konica) from 1925 to the early postwar period. The Pearlette is historically significant as the first mass-produced Japanese camera.

General description

The Pearlette is a near-copy of the Piccolette by Contessa-Nettel, itself inspired by the Vest Pocket Kodak. The camera is easily recognized by the name Pearlette under the lens.

The front standard is mounted on a pair of scissor struts and extends to the bottom, acting as a standing leg. There is a round cut-off on each side of the body to pull out the front standard easily. A pivoting brilliant finder is mounted on one corner of the front plate. There are two tripod threads: one is at the bottom right, as seen by a photographer holding the camera vertically, and the other is on a strut joining the two sides of the trellis structure at the bottom. Most of the other features evolved during the camera's very long production run.

The regular models have a fixed-focus lens, either a simple meniscus achromat lens (usually US 8, i.e. f/11) or a triplet lens (f/6.8, later f/6.3). The shutter is a Woco by Wollensak or a Pegasus or Echo by Konishiroku, depending on the year of production. All have three speeds: 1/25, 1/50 and 1/100.

A special edition called the High-Grade Pearlette was also offered for a short time with higher lens and shutter specifications.

First generation: side loading

The first generation models have a removable side plate for film loading, and an advance key at the top left. They always display an RK logo on the front plate, opposite the brilliant finder.

Wollensak lens and shutter

The Pearlette was introduced in June 1925. The original model is mainly recognized by the absence of a wireframe finder. Other specific features are the sliding button used to open the side, and the thin rim around the finder window, surrounded by three small screws. The fixed body side is engraved PEARLETTE, and has a silver tripod attachment retained by three screws. The back has a removable disc containing a single red window.

The shutter is a N°0 Woco shutter by Wollensak, marked N°0 WOCO above the lens and WOLLENSAK U.S.A. below. The speed is set by an index at the top, and the aperture scale is at the bottom. On the original version, the available speeds are T, 25, 50, 100. The camera exists with a Deltas Aplanat 75/6.8 lens or with a meniscus achromat lens whose aperture runs from 8 to 64 in the Uniform scale.

A wireframe finder was added in 1929. The wireframe is hinged to the front standard and supports a close-up lens in the middle: when the wireframe is in the folded position, the close-up lens stands in front of the taking lens. There is a simple eyepiece attached to the camera's back.

In 1931, the wireframe hinge was reinforced and the front plate was enlarged a little.

Pegasus shutter

The imported lenses and shutters were replaced in 1932 by equipment made by Rokuoh-sha. The Pearlette has a Pegasus shutter giving B, 25, 50, 100 speeds. The shutter plate is mottled and marked PEGASUS at the top and ROKUOH-SHA at the bottom. This version exists with a Hexar Ser.II 75/6.3 lens and with an f/8 meniscus lens, said to be made by Asahi Kōgaku.

An additional close-up lens for the brilliant finder is attached to the front wireframe,.

New model: hinged back

The new Pearlette model, released in 1933, has fixed side plates and the back is hinged to the bottom. There is an advance knob at the top right and a tripod screw at the bottom right, as seen by a photographer holding the camera vertically.

This model was first sold with the Pegasus shutter but it was soon replaced by the Echo shutter. The shutter plate is black with a chrome rim. It is marked Echo at the top and Rokuoh-sha at the bottom and the position of the controls is the same. This version with Echo shutter exists with an Optor 75/6.3 lens or an f/8 meniscus lens, both said to be made by Asahi Kōgaku.

The shutter plate was changed in 1937, with a metal stripe on each side. The markings on the front plate were changed in 1940, with the disappearance of the logo and the adoption of a Pearlette name plate screwed to the bottom of the front standard.
