The Silverflex (シルバーフレックス) is a Japanese 6×6 TLR made in 1953–4 by Nippon Kōki. This company was also making the Silver Six 6×6 folder at the same period.

General description Edit

The Silverflex is a plain copy of the Ricohflex VI. The taking and viewing lenses are externally geared for focusing. The distance scale and depth-of-field indications are engraved on the upper lens. The viewing hood contains a large magnifying lens. The film is advanced by a knob on the photographer's right. The advance is controlled by a red window in the back, protected by a vertically sliding cover. The exposure chamber comes out together with the spool holders for film loading.

The lenses are 80mm f/3.5, and the marking is SILVER ANASTIGMAT on the taking lens and SILVER VIEWER on the viewing lens. The shutter is of the setting type and has flash synchronization. The release lever is attached to the shutter casing itself.

It is said that the build quality of the Silverflex is poor, far from that of the Ricohflex.[1]

The Silverflex Model S Edit

The Silverflex Model S was first announced in Japanese magazines dated September 1953.[2] The announcement in Asahi Camera says that the manufacturer was known for its Silver Lucky enlargers, and that the Silverflex was its first camera.[3] The document mentions a limited range of shutter speeds (B, 25, 50, 100) and a price of ¥8,500.

The advertisements published in Asahi Camera from September to November 1953, reproduced below, give the same price and characteristics.[4] The September issue contained a special lottery ticket for owners of the Silverflex, offering various lots, ranging from a Silver Pigeon scooter to a free single issue of Asahi Camera.

The leaflet reproduced below is specifically about the Silverflex Model S, and mentions B, 25–100 speeds. The picture is the same in all the documents. It shows B, 25, 50, 100 speed settings, an ASA synch post and taking lens no.195143C.

The January to April 1954 issues of Asahi Camera show a newer advertisement, displaying a range of cameras by Nippon Kōki. The price is unchanged but the range of speeds is now B, 10–200.[5] In all the advertisements, the camera is only called "Silverflex" (シルバーフレックス) and the full name only appears on the camera's nameplate as SILVERFLEX MODEL S.

Some actual examples have an NKS shutter (B, 10–200) with flash synchronization, marked NKS at the bottom of the speed rim and at the top of the shutter plate.[6] Early ones have an ASA synch post,[7] later ones seem to have a PC socket.[8]

The Silverflex Model L and Model LII Edit

One example of a Silverflex Model L has been reported, with an S.S.S. shutter (B, 1–200) and lens no.6113.[9] This number indicates that the camera went after Model S. It is likely that the only difference with the previous model is the new shutter with slow speeds.

Finally, the Silverflex Model LII pictured above is the only example of its kind found so far. It has an S.S.S. shutter with self-timer and PC socket. Its features seem similar to the Model L, but for the nameplate inscribed SILVERFLEX MODEL LII.

Notes Edit

  1. On p.443 of Kokusan kamera no rekishi, Orima Isamu (織間勇), who was an engineer at Riken from the 1950s, says that the build quality of the Silverflex was appalling. The same kind of comments also appear in this page by Oozusi.
