Thanks!
If you're used to shoot with many different lenses your used to use different positions for you hands, just look at the tele and tele zoom lenses, they are very different in how far away the zoom or focus rings are from the camera
BTW the Canon guy here in the video has the lens foot in the wrong position, it should point down, like feet normally doo,,,
The lens foot should rest in the palm of your left hand, like always with the Nikkor 70-200mm lenses, and rotate it when use in portrait mode
