There you go... "shoestring marketing budget". I am NOT arguing that the cameras are poor or not worthy - there are too many examples of photographers who demonstrate they are great cameras*.
I AM arguing that they are not going to get the visibility of Canikon to the wider public without a much greater investment in marketing, and their product investment is IMO a bit off-beam for global domination. Although I am sure the 645 is a great MF camera, this is a specialised market relative to the DSLR market (and only released in the US after much clamoring over there - not indicative of a very proactive company.) Note that Nikon are where they are without an MF offering at all. The K5 is certainly getting some traction, but it needs more than great technology and high DxO scores to break away from a small, dedicated market segment.
(BTW, the "hoya not committed" comment was taken from Trublubiker earlier in the thread. I have no idea.)
*EDIT: I don't mean to imply that the camera makes the photographer either - more that there are photographers who know their gear and reckon the Pentax is good.
