Update 2: Canon has officially announced the development of the Canon EOS-1D X Mark III. Some original rumors about the camera look to be incorrect. There will not be a new battery and the top-down LCD looks to be the same. What is interesting is the new AF-ON/Smart Controller button, we have seen it in a photo we're unable to publish and the button area is a lot bigger than on previous cameras. The AF-ON/Smart Controller button is there in horizontal and vertical orientation.
Update: Almost immediately after we posted this report, we were told by an anonymous source that Canon will address the EOS-1D X Mark III very soon. Is there a development announcement coming? We have not confirmed this with any known sources yet.
A few weeks ago we reported the first rumored specifications for the upcoming Canon EOS-1D X Mark III. Since then, a few more things have trickled in about the camera.
There will be a new battery for the Canon EOS-1D X Mark III, and it will have a “new feature”.(False)
- Optical viewfinder, but there will be more information available within it.
- 61 autofocus points, all cross-type with a “slightly” larger spread
Similar top-down LCD to the EOS R(False)
I'm sure more information will continue to trickle in for the next few months.
