Bloomberg reports that Yutaka Yamanaka, the grandson of the Hoya Corp. founders is not happy with the $1billion purchase of Pentax and describes it as “overpriced” and "failure". This is not really surprising and all stories about Hoya trying to sell Pentax are probably more than just a rumor (via pentaxforums).
Another Pentax related rumor: there is a thread in the PentaxForums that the 50mm lens will be discontinued this Fall and Pentax will move forward with the 55mm model.
