BBC R&D: Assessment and settings for Sony PMW-EX1 and EX3

Posted on February 25, 2009 in General Production | 1 Comment

The BBC Research and Development department takes apart the Sony EX1 and EX3 cameras for this extremely detailed white paper:

…The cameras are relatively light (about 2.8kg in including battery) and have an integral viewfinder (3½” lcd), and seems aimed at the high-end professional and full broadcast markets, even though the broadcast market would normally demand an image format larger than ½” and removable lens, and a recording format with higher bit-rate. The EX3 has genlock and time-code inputs, and a remote control socket, so may well be usable in multi-camera shoots.

Variable speed recording is possible, from 1 frame/second up to the nominal frame rate setting (24/25/30 when recording 1080-line, 24/25/30/50/60 when recording 720-line). The implications, for production at 25p, of setting the camera to 720p/60 and then recording a variable frame rate, have yet to be established. Perhaps the only problem would be timecode and genlocking.
