The Roll Light Ref (ロールライトレフ) is a Japanese 4.5×6 camera shaped like a TLR, made by Ōhashi Kōki Seisakusho in 1937. It is called Roll Light Ref in advertising documents but the camera itself is only marked "Roll Light".
Description[edit | edit source]
The Roll Light Ref has a metal body, with a large hexagonal front plate, meant to look like the first model of the Ikoflex. There is an advance knob on the top right of the body and three other knobs holding the film spools on both ends. The camera body seems to have some similarity with the Union Ref and Hansa Rollette Ref, but it is difficult to say more without a closer examination of the cameras.
Two models of the camera have been observed. In both cases, it is not entirely clear if the camera is a real TLR or a pseudo TLR. It seems that the name ROLL LIGHT is embossed in the leather below the taking lens on all the models.
First model[edit | edit source]
In the first model, the nameplate is written Roll Light and is partly hidden by the hexagonal front standard, and the viewing hood has an X-shaped rib.
It seems that focusing is done by a lever protruding from the side of the front standard and actioned by the user's left hand, while the shutter release is directly mounted on the shutter housing. It also seems that the taking lens and shutter assembly is attached to the front standard and that the whole plate moves back and forth when focusing. An original leaflet states that the camera has helical focusing (ヘリコイド, as opposed to front-cell focusing) to one metre. It is not clear if the viewing lens moves for focusing too or if it is attached to the body, thus making the camera a pseudo TLR. No distance scale is visible and it is not known how the focus is controlled.

- Genira Special f/6.3 lens, Genira shutter, 25, 50, 100, B speeds (¥25);
- Genira Anastigmat f/4.5 lens, Light C shutter, 25, 50, 100, T, B speeds (¥43);
- Genira Anastigmat f/4.5 lens, Light B shutter, 5–250, T, B speeds (¥49).
The leaflet only mentions the first two versions, and it also says that the company was clearing the stocks and applying a 50% discount to the Baby Light and Roll Light Ref. In both documents, the advertising pictures show the variant with f/6.3 lens. The shutter plate is marked GENIRA–SHUTTER at the top and OKS at the bottom. ("OKS" probably stands for Ohashi Koki Seisakusho.)
One example of this version has been observed, again with the f/6.3 lens. It is similar to the advertising pictures, except that the shutter has a T setting and that the shutter plate has a white rim and is only marked GENIRA at the top.
Second model[edit | edit source]
The second model has a different viewing hood, with a square portion that is slightly higher than the rest and a logo in the middle reading EIN.
It seems that the hexagonal front standard is now fixed and that only the shutter and taking lens are moved for focusing. It seems that a hole is cut in the front standard around the viewing lens, which perhaps moves together with the taking lens. However Sugiyama says that the viewing lens is fixed.
One example of this version has been observed with a nameplate marked ROLL LIGHT in capital letters. This nameplate is different from the nameplate of the previous model, and it is shaped so that the marking is always visible. The shutter is a Gelmer, reportedly giving T, B, 25–150 speeds. The shutter plate is marked GELMER at the top and perhaps GELMER Mfr at the bottom. (A similar shutter is known on the Semi Shiks.) The lens is reported as a Gelmer Anastigmat 75/4.5.
Another example has been observed with no nameplate at all. It has the same Genira 75/6.3 lens and Genira O.K.S shutter (T, B, 25–100) as described for the previous model.
