Sony says there is no collaboration with Olympus on the camera business (and hints some medium format poker face)
Sony unveiled at DSLRmagazine (google tranlsation) that they still are not working together with Olympus when it comes to develop cameras. For now the only real collaboration is on the medical business.
An interesting “psychological” analysis from DSLRmagazine. When they asked Sony about a possible future RX medium format camera Sony didn’t answer but the “poker face interpretation” from DSLRmagazine makes them believe the camera is coming for real :)
