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.
