Tim Smith from Canon says that 4K is here to stay. Canon currently has two cameras that record 4K the EOS 1DC and the EOS C500. The 1DC records 4K within the camera with a form factor that that is very similar to a Canon 5D Mark II or 1D. The C500 has a larger form factor and is similar in size to the Canon C300. The C500 offers 4K recording to an external field recorder like the Convergent Design Odyssey 7Q.
