With the specifications of the EOS-1D X Mark II being made public, the obvious next question is what can we expect to see in the EOS 5D Mark IV, which is coming in 2016.
The EOS 5D Mark III followed the EOS-1D X quite closely in on paper specifications. Below is a prediction based of what we think we could see inside the next 5D.
- DIGIC 6+ (They won't launch DIGIC 7 so closely to a flagship camera)
- 61 point AF
- CFast & SD
- Built-in GPS & Wifi
- Lighter weight
The biggest question will be in regards to 4K video capture. It appears that on the EOS-1D X Mark II, you will be able to record 4K video to the CFast 2.0 slot. Will Canon put a CFast 2.0 slot in the 5D Mark IV along with the SD card slot and do away with CF? I don't see them taking the SD card slot out of the camera in favor of dual slots for CF and CFast. Everyone we've spoken to has said 4K recording will not be part of the EOS 5D Mark III direct replacement camera, but that can obviously change.
A video oriented version of the 5D such as a 5D C? It's possible and has been long rumored, but nothing reported can be considered reliable at this point.
