DVW-790WS
Digital Betacam Camcorder
This digital camcorder combines a color video camera, which uses IT type Power HAD sensor CCDs, with a Digital BETACAM series portable videocassette recorder. Its excellent image quality, sensitivity, portability, and dust- and water-proof construction make it ideal as a camcorder for ENG and EFP.
The introduction of a new method of processing digital signals improves the image quality even further and makes the camcorder far easier to use. The DVW-790WS employs FIT type Power HAD sensor CCDs featuring a lower smear level and the ability to switch between the conventional aspect ratio of 4:3 and a wide screen aspect ratio of 16:9.
