Pentax working on second generation of the 645D medium format camera
The sensor inside the Pentax 645D camera ($9,995) was initially produced by Kodak, but in 2011 they sold the Image Sensor Solutions (ISS) business to Platinum Equity. The rumor is that those medium format sensors are not longer in production and Pentax is working on a second generation of the 645D camera. It seems that Leica is having similar issues and will be using a new sensor from an European semiconductor manufacturer in their upcoming S3 camera.
