Nevertheless, I attended the "Salon de la Photo" in Paris today (will go tomorrow also) where basically every huge brands come out and give you goodies, exposes new features, make you try out amazon lenses and blablabla...
I was listening to some random Canon guy performing on the 5DmkIII when he literally said this in front of the audience this French: "je n'ai aucun doute que le monde de la photo accueillera le 5D mark IV avec un énorme enthousiasme".
Translation: "I have no doubt that the world of photography will welcome the 5D mark IV with great enthusiasm". I cannot tell why he said this in comparison to 5DmkIII, I was barely listening to his performance, but my eat catched this.
Now, I just heard this and did not modify any of his words, and I am simply writing down in M&A what I heard from a Canon guy.
So, lets wait and see.
