Gelmer shutter[]

The Gelmer shutter is known on the Semi Shiks by Kigawa and Roll Light Ref by Ōhashi. It gives T, B, 150, 100, 50, 25 speeds. The shutter plate is inscribed GELMER at the top and GELMER Mfr. at the bottom, perhaps for Gelmer Manufacturing. The speeds are sometimes inscribed on the shutter plate and sometimes engraved on the shutter rim.[1]

Gelmer lens[]

A Gelmer Anastigmat 75/4.5 lens is reported on the Roll Light Ref.[2]

Gelmer or Gelmar filters[]

Filters called Gelmer or Gelmar were distributed by Eikōdō in the late 1930s and early 1940s. Advertisements dated between June 1938 and October 1943 have been observed.[3] The name is consistently written ゲルマー in katakana. The Roman spelling GELMAR appears on some advertising pictures, but some descriptions have the Roman name "Gelmer", perhaps by mistake.[4] The filters are mentioned as "made in Germany" (独逸製) from 1938 to 1940, but this mention was later suppressed.

Germa cameras[]

The name Germa on the Baby Germa and Semi Germa cameras is written ゲルマー in katakana, this is easily confused with Gelmer. These cameras were made by Tōkyō Shashin Kōgaku and distributed by Kigawa.
