In the Sundance Day Three report at HD4NDS, Mike shares some details on the new F23 CineAlta camera from Sony.

*24p capable
*2/3″ 3 CCD 1920 X 1080 imagers (with improved dynamic range over the F950)
*Can do 10 bit 4:4:4 up to 30 fps and 10 bit 4:2:2 up to 60 fps.
*14 Bit A/D
*Single or dual link HD-SDI, fiber optic tether solution in the works (available later)
*Framerate speed ramps are possible in-cam
*Records to SRW-1 HDCAM SR deck (can be mounted on top, in back or via tether)

Sony has made it clear that this model is not intended for the “digital cinema” market, but for high end video instead. Think “24″ or “Battlestar Galactica” production. I’ve also read that the B4 lens mount has been rebuilt with stronger and more temperature-stable material than the 900-series cameras.
