The B Pearlette or Pearlette B is a Japanese folding camera taking 4×6.5cm exposures on 127 film. It was released by Konishiroku (predecessor of Konica) at the end of 1935.[1]

Description of the body

Despite its name, the B Pearlette has nothing in common with the strut-folding Pearlette. It is a cheaper camera, self-erecting with a folding bed. The body has a sharp octagonal profile and there is a folding frame finder attached to the side. The back is hinged to the bottom and contains two red windows for film advance. There is a nameplate attached to the top of the lens standard, marked Pearlette. B or B. Pearlette depending on the examples.[2]

Lens and shutter equipment

The shutter is an everset Primer giving B, 25, 50, 100 speeds selected by an index at the top. The shutter plate is black, marked Primer at the top and ROKUOH-SHA at the bottom. The lens is a simple meniscus and the aperture scale is at the bottom, marked U.S. with 16, 32, 64 settings (these are "Uniform System" apertures, corresponding to f/16, f/22 and f/32 in the usual aperture scale).

Advertising

The camera was featured in the new products column of the November 1935 issue of Asahi Camera and briefly advertised at the end of 1935.[3] An advertisement dated December 1935 listed the camera as the B Pearlette, for ¥9.50.[4]
