The Silverflex (シルバーフレックス) is a Japanese 6×6 TLR made in 1953–4 by Nihon Kōki.

General description

The Silverflex is a plain copy of the Ricohflex VI. It has externally geared lenses for focusing, and 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 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 S

The Silverflex S was featured in Japanese magazines dated September 1953.[2] An advertisement in Asahi Camera of the same month gives the price of ¥8,500 and says that the shutter has 25, 50, 100 speeds and is synchronized for flash.[3] In an advertisement in the January 1954 issue of the same magazine, the price is unchanged and the range of speeds has become B, 10–200.[4] In both advertisements, the camera is only called "Silverflex" (シルバーフレックス) but the nameplate reads SILVERFLEX MODEL S.

The cameras observed so far 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.[5] The early cameras have an ASA synch post and later ones have a PC synch socket.[6]

The Silverflex LII

One example of the Silverflex has been observed with a nameplate inscribed SILVERFLEX MODEL LII.[7] The only visible difference from the previous model is the shutter name ending in "S.S.", and the presence of a self-timer. (The shutter might be the S.S.S. also observed on an example of the Carl Six.) The later lens number indicates that the model LII went after the model S.
