I found that it was a real wrestling match to rotate my Nikon 80-400 to shoot a vertical so a tour leader told me about a Kirk foot. Go to kirkphoto.com and look for NC-80-400GN. I ordered it the day I got home and what a world of difference! My lens rotates very easily now. Good luck!
This is what I used to carry around my 200-500.
