The webmaster of this site.

My name is Hugo Ruys. I am a Dutchman, born in 1938. Since about 1975 I have collected all Ihagee products, many Exakta lenses, all Ihagee equipment and most non-Ihagee equipment for Exakta.

More important, I collect information about the history of the Ihagee company (East and West) and its founder/owner Johan Steenbergen, I write articles about it and will make (part of) this available to you on this site.

I try to keep in contact with other collectors by being member of the British Exakta Circle and the French Exakta Ihagee Club de France (EICF), and by maintaining a list of Dutch Ihagee collectors (this list is not a club; most of them are members of the Dutch Society of Photographica Collectors "Fotografica").

I also maintain contact with the family of Steenbergen, in particular with the boards of the Steenbergen Stichting (=foundation) and the Stichting Steenbergen Caerus, and represent the Ihagee Collectors of the World (you) when the Steenbergen Stipendia are handed out to the best Dutch photography student of each year.

In 2016, the host registration and domain name were transferred to Mr. Dikkers, as representative of the Stichting Steenbergen Caerus. This foundation has pledged to maintain the content and keep the site available on the internet in order to allow collectors on-going access to its rich database of historical information about the Ihagee, its founder and Exakta.

Problems, questions, additions or remarks

Problems with opening some items

Many items (files) are in .pdf format, which means that you need the program Adobe Reader (version 3.0 or higher) to read them.
If Acrobat Reader is installed on your machine, it should start automatically when you click on the item.
------- NB This works with Internet Explorer, but I'm not sure about other browsers.
------- Adobe Reader is absolutely free.

Remarks or questions in general

If you have remarks or questions about Ihagee, its products and history, its founder Johan Steenbergen or about this site, please send me a message. E-mail is the fastest and cheapest, but there are other ways.
You may address me in Dutch, English or German. In writing and if you keep it simple, French, Norwegian, Swedish and Danish may work as well. I prefer to answer in English or Dutch; German is also possible.
