I hope someone from Canon actually reads these posts. I own a studio, and shoot about 90% of my work tethered. I would very much like to see you put in a faster port for tethering into the 5d MKIV as well as a new 1D body. With the introduction of the new USB 3.1 technology, this would be a huge help in my studio. Even just 3.0 would be better than the dreadfully slow 2.0 in the 5d mkIII. Please and thank you!
