 The PMW-EX1 utilizes Sony's three 1/2-inch type "Exmor" CMOS sensors, each with an effective pixel count of 1920 x 1080.Coupled with signal processing LSI, the PMW-EX1 produces images in 1080p (30 and 24 frame/s), 720p (up to 60 frame/s) and 1080i (up to 60 frame/s) HD.The Sony EX1 records internally to SxS (S by S) cards and does not internally record to tape (an external tape device would be required).
