Originally posted by reh321 No - the "Pentax" brand has been sold, but only twice now. The medical brand and the camera brand are now owned by separate companies, but only Hoya and Ricoh use the name, and only Ricoh uses it for photography per see. That is a complete different process than what was done to poor old Polaroid after their bankruptcy.
There are actually at least five companies that use the Pentax brand in their respective field(s):
1. Ricoh for photographic equipment and binoculars
2. Hoya for medical products (Pentax Medical)
3. Pentax Industries Spa, an Italian company, for hydraulic pumps
4. Diewe - Diamantwerkzeuge GmbH, a German company, for abrasive tools
5. SPX Flow, a US company, for mixing, kneading and attritioning machines and sifters.
The first two obviously emanate from Asahi Optical: Asahi Optical (renamed Pentax in 2002) ==> Hoya (sale and merger; that was the one and only sale of the Asahi-trademarked Pentax brand) ==> Ricoh (licence agreement). I don't know for the other three.
