A new scoop this weekend has shown Sony developing its own 3D pro camcorder. The EX3 would combine two of its similarly named studio cameras into a single camera that could generate stereoscopic images. Each CMOS sensor can output full-quality 1080p, 4:4:4 video over their own distinct HD-SDI outputs, the Engadget source said, or squeezed 4:2:0 MPEG-2 video to SanDisk- and Sony-made SxS cards.
