We're told that the Canon EOS 5D Mark IV will be announced on August 25, 2016 if you're based in North America.
The camera will be launched with a new EF 24-105mm f/4L IS II kit along with another current lens kit.
We're not sure if the new EF 16-35mm f/2.8L III will be announced the same day, or get a separate announcement ahead of Photokina.
I don't know what time of day the announcement will come on August 25, 2016, it could be at 11PM EST, as they have done before. This would make it an August 26, 2016 announcement for a lot of the planet.
Lots more to come…
