The Elka was a Japanese leaf shutter made in the 1930s.
See also the Semi Elka, a 4.5×6cm camera made in 1941.
The maker of the Elka shutter is not known for sure. Some versions have T.B.C.T. markings or a TB logo.
A Semi Elka 4.5×6cm camera is reported in the official price list dated November 1941, where it is attributed to the company Banno Toyoji Shōten, which is otherwise unknown. The "TB" logo might stand for Toyoji Banno, but this is merely a guess.

It seems that the first versions of the Elka shutter were dial-set, up to mid-1936, and that it became rim-set after that date.
The early dial-set Elka has 25, 50, 100, B, T speeds selected by a flat wheel at the top. The name ELKA is inscribed in capital letters on the speed wheel cover and the initials T.B.C.T. are written in small capital letters underneath. There is a hole under the lens for a thread and needle release device, and no logo is visible.
The late dial-set Elka has the same speeds engraved in the reverse order on a conical wheel, engraved ELKA at the front. The hole for the thread and needle release is at a slightly different location, and the front plate has a TB logo on the right.
The plain Elka has B, 25, 50, 100 speeds set by an index, and the name Elka in small letters at the top of the shutter plate. Some illegible text is also written at the bottom.
The Elka-C has 10, 25, 50, 100, 150, B, T speeds set by turning the rim. The front plate has the words Patent–Pending at the top, ELKA–C at the bottom and a TB logo on the right. One example is known with the same name and markings but 100, 50, 25, B, T speeds only; however this particular example was crudely repaired during World War II, and its speed rim was perhaps substituted.
An Elka-B is also reported, giving T, B, 5–200 speeds, but has not been observed so far.
This list is incomplete, and not all the versions of the cameras listed have an Elka shutter:
- Kinka D
- Kinka Roll
- Kinka Lucky
- National (4×6.5)
- Need plate folder
- Sun plate folder
- Super and Special Super plate folders
Associated with an unknown lens
In the advertisements, the Elka shutter is often associated with a lens called トリオナー (torionā) in katakana script. The corresponding Roman spelling is unclear, and is discussed in the Trionar page.
- The name is hardly legible as 伴野豊治商店. This might read "Tomono Toyoji Shōten" as well.

- Kokusan kamera no rekishi, p.388 (item 157), says that the July 1936 advertisement in Asahi Camera for the National (4×6.5) shows a shutter of the "old Vario type" whereas the following ones show a shutter of the "new Vario type".
