Vintage lens makers – Astro-Berlin (Germany)

/ spqr / 2 Comments

Astro-Optik is one of a number of German optical companies that flew under the radar, due to its speciality lenses. It was founded in 1922 as Astro-Gesellschaft Bielicke & Co and based in Neukölln, Berlin (which would become part of West-Berlin). The founders were William (Willy) F. Bielicke, Hugh Ivan Gramatzki and Otto (?). Gramatzki (1882-1957) was a successful amateur astronomer and astrophotographer who published in the journal Astronomische Nachrichten, and headed the local branch of “Berliner Astronomische Vereinigung” for a number of years. Gramatzki invented the Transfokator in 1928. Bielicke (1881-1945) a German-American optical designer was involved in the technical development of the lenses and was responsible for the “Tachar” and “Tachon” lenses.

The 1000mm lens

So it is then not surprising that Astro-Berlin’s product range included lenses suitable for astrophotography and astronomical photometry. After the war the company focused on its film technology (Astro-Kino, Astro-Kino Color) developing lenses that had long and extremely long focal lengths, sometimes called “optical heavy artillery”. The company ceased operations in 1991.

The company produced a multitude of lenses, many under the brand Astro-Berlin. Astro-Berlin is likely most famous for its long lenses for cinematography and photography. These lenses were very simple consisting of one (f/5, f/6.3) or two (f/2.3) achromatic doublets. The f/5 lenses for 35mm came in 300mm, 400mm, 500mm, and 640mm lengths. The 800mm f/5 lens was designed for medium 60×60mm format, and the 1000mm f/6.6 for 60×90mm format.

In addition they produced quite fast lenses. In 1933 they introduced the Tachor f/0.95 which was available in various focal lengths. The 75mm version was suitable for an 18×24mm format (half-frame) but it was a large lens at 110mm in length with a frontal diameter of 81mm. The longest lens produced was possibly the 2000mm f/10 Astro Telastan. At times Astro also cooperated with the other Berlin optics manufacturers Piesker and Tewe.

These days, Astro-Berlin lenses are expensive on the secondhand market. For example the Astro Berlin Pan Tachar 100mm f/1.8 can sell for up to C$6000 depending on condition. However it is possible to find a 500mm f/5 lens for between C$900-1200.

Vintage lens makers – Komura (Japan)

There are some lenses that few people have ever heard about, usually because they provided third-party lenses for many differing camera mounts. One such lens brand is Komura, manufactured by Japanese optical company Sankyō Kōki K.K. (Sankyo Kohki), known in English as Sankyo Koki Co. Ltd. In 1962 the company, registered the US trademark Komura, indicating that it was firat used as a trademark in 1953. Before that it is believed the company use the brand name Chibanon or Chibanone. By the 1970s, the company had changed its name to Komura Lens Manufacturing Ltd.

The Komura literature touted their lenses as being “superbly sharp”. They seem to have produced at least 40 different lenses from 28mm to 800mm, for SLR, rangefinder, and C-mount cameras. Their 28-200mm lenses were made with direct individual mounts, mostly in the Leica thread mount and Nikon rangefinder, but also M42, Exakta, Nikon F, Minolta, Miranda, Konica, Canon, Pentax and Petri. Those from 200-800mm had a generic 47mm screw mount which required a specific adapter, called a ‘Unidapter’ to convert them to other camera mounts (apparently to reduce inventory requirements).

Today Komura lenses are little known, but can still be found, especially for Japan (eBay). A 105mm f/2 is usually advertised for between C$300-500, while 85mm f/1.4 lenses seem to go as high ac C$1200. Actually quite high prices for a brand that doesn’t have a lot of presence. To put this into perspective, the Komura 800mm f/8.0 sold for US$695 in 1965 (plus $8.50 for an appropriate adapter). Conversely the 500mm f/7.0 sold for US$175 (+ $4.95 adapter). The 85mm f/1.4 sold for US$162.
