The EOS-5D Mark IV is Canon's most anticipated pro camera after the EOS-1D X Mark II because it promises a continuation of the highly successful EOS-5D line into a new decade. You can see the photos, expected specs plus the two EF lens that will be announced at the same time, in my earlier posts.
Canon's announcements for 2016 is not over yet. There may be a new EOS-M camera coming before the end of the year. Perhaps just before the CES Show in Las Vegas on January 5, 2017. This will not be the full frame mirrorless model. Instead it will have the APS-C sensor. There will be a few new EF-M lens to go with the launch and I doubt the new camera will have 4K video.
Keep checking back for the latest info. I will update my readers as soon as I receive them.
