The video on tops shows you the new 4K Sony prototype. While there are no official specs the camera is “rumored” to have an FZ mount (like the F5 and F55 Cinealta cameras) an 8 Megapixel sensor and definitely no SLT or optical mirror. This is a pure mirrorless camera with Electronic Viewfinder. It’s going to be release sometimes in 2014 and it will compete against the Canon EOS-1D C .
I am not a big fan of videocameras with DSLR shape. Doesn’t really make a lot of sense. I think Blackmagic did a smarter move with the Pocket Cinema Camera ($955 at BHphoto). A compact video only mirrorless camera with CineRAW DNG recording and 220MBs Pro RES. Sony should so a camera like that in E-mount!
