Phase One P30

P30+ on Phase One 645 DF

The Phase One P30 and the Phase One P30+ are medium format digital backs. That means that they are media (image sensor), image-processor, control-screen panel and storage device in one module for usage on modern medium format camera systems like Phase one's Phase One 645 DF. The modules use ([[probably Dalsa's) 44x33 mm 31 Megapixel 16 bit-Opticolor image sensors. They are made for exposure times from 1/10000 sec. to 1 hour.
