Ishii Shōkai was a Japanese distributor in the 1930s and 1940s. It used the brand name Echt on a number of products, and was running a dependent manufacturing branch called Echt Kōgaku Kōgyō in the early 1940s.


The brand name Echt (エヒト, Ehito) was first used by the company Ishii Shōkai (石井商会) in the late 1930s. The January 1939 issue of Asahi Camera features Echt film magazines for 35mm cameras, distributed by Ishii.[1] Some months later, an advertisement dated December 1939 says that Ishii was the maker and distributor of the Echt products (エヒト製品製造発売元), and shows the ECHT logo, with the letters E, H, T circled by a large oval C.[2] The company was based in Ginza,[3] and was offering various high-end accessories mostly copied from the Zeiss Ikon range. The company was also selling genuine Zeiss products along with the domestically made copies.Cite error: Closing </ref> missing for <ref> tag In January 1942, the Kraft camera and the Echt (エヒト) enlarger were jointly advertised by Echt Kōgaku Kōgyō Y.K. (ヱヒト光学工業有限会社, literally reading Ehito Kōgaku Kōgyō Y.K. and meaning Echt Optical Industries) and Y.K. Ishii Shōkai (有限会社石井商会, meaning Ishii Trading).[4] The two companies had the same physical address and were obviously closely related.[5] The company names indicate that Echt was the manufacturer and Ishii the distributor. (The April 1943 government inquiry on Japanese camera production mentions the Kraft camera as made by Ishii and distributed by Echt, but this was surely by mistake.)[6]

Ishii Shōkai survived the war, and placed advertisements in the March and April 1946 issues of Ars Camera.[7] These documents say that the company was ruled by Ishii Yūzō (石井有三), certainly the founder, and make no mention of the Echt products.

By 1955, the name of the company was K.K. Echt Shōkai (㈱エヒト商会).[8] It was selling an Echt exposure meter, which displays the same logo as the prewar and wartime accessories.[8] All trace of the company is lost after that date.

Mikami Makoto (三神誠), founder of the Matsushima camera distributor, was a former employee of Ishii, and Nukui Teikichi (貫井提吉), founder of the Nukui Labo repair shop, was a former employee or subcontractor working on Echt products.[9] The two men made acquaintance at Ishii, and it was Nukui who introduced Ogihara Akira (荻原彰), founder of Orion Seiki to Mikami, who would distribute Orion and Miranda products for various years.[9]



The most complex Echt device known so far is a copy stand for the Contax, called "automatic focusing copying device" (自動焦点式接写器). It is a close copy of the reproduction stand 5520/1 made by Zeiss Ikon. It comes in a black box, with two stages to contain the various components of the set. The green velvet lining inside the box lid shows the ECHT logo, the Japanese characters エヒト, the device name, the company name ECHT KOGAKU and the address GINZA TOKYO. The name ECHT WORKS is inscribed on the base of the copy stand, together with Echt's logo. The particular example pictured in this page has number 106 engraved at the back of the base and on the fixed and moving parts of the column, and number 282 engraved under the base. The device was certainly produced in very small numbers.

Other Echt accessories have been observed:

  • a set of filters for the Leitz Summar 5cm f/2 lens; it is contained in a box marked ECHT–Filtersatz and each individual filter is marked Summar 1:2 F5cm;
  • a portable copy stand complete with close-up lenses, whose user manual shows the name "Echt repro device for Leica" (エヒトライカ用接写装置); it includes a special adapter ring for the Leitz Elmar 5cm f/3.5, marked ECHT Elmar 3.5; the name ECHT WORKS and the address GINZA TOKYO are inscribed inside the box, together with the ECHT logo and the Japanese characters エヒト.

Further accessories are known through original documents only:

  • a complete close-up device for the 6×6 Super Ikonta (c.1939), said to "replace the Contameter" (コンタメーター代用), including a portable copy stand (similar to the "repro device for Leica" described above), close-up lenses and optical elements to correct the parallax and/or rangefinder adjustment;[2]
  • close-up lenses alone (c.1939), similar to those included in the above sets;[2]
  • a focusing rail (c.1939), apparently copied on a Zeiss Ikon accessory;[2]
  • film cassettes for 35mm cameras (c.1939), available in Contax and Leica versions.[1][2]
  • Echt exposure meter (sold ¥4,500 in 1955)[8]
