Digital cameras: Ricoh buys Pentax - Golem.de. Hmm, this could really become interesting, as both Pentax and Ricoh have a lot of interesting ideas. And Pentax also brings the necessary photographic know-how (which is also present at Ricoh, but rather at an "amateur" level). The question then, of course, is what will happen to things like the Pentax Q and Ricoh GRX - they are at least overlapping in their offerings.
