I think we could be seeing the end of the smaller SLR manufacturers.
Contax - dead
Minolta - sold out to Sony
Pentax - Selling out to Hoya
Yashica - who?
Nikon - keeps making bad business decisions.
Canon - keeps on going.
Kodak - dumped dSLRs.
Fuji - trying hard
What about Olympus?
Have Fun,
I found this on Hoya's website. Hoya did NOT "swallow up Pentax"
