Sony has shown prototypes for two new 4K cameras at NAB 2013.
The National Association of Broadcasters show takes place in Las Vegas, Nevada. Sony announced in its press conference the two new 4K camera prototypes along with news that there will be a wide variety of lenses released for the cameras in the future.
For now, these two new cameras are a long way off being available to the public. It is thought that the cameras will be competitors for Canon's EOS 1D range of DSLRs.
No specifications or further details are available about the cameras at this time.
