the thumb thing helps (along with the grip) to maintain a firm hold but it also keeps the thumb away from hitting the back of the camera. .....
Joe: I will try one of those thumb things but it is necessary for me to have a firm grip with my thumb on the back of the camera at all times since my only contact with the camera for 6-7 hours at a time is my fingers wrapped around the grip and my thumb on the back. I don't use straps but simply always carry the camera like that in my extended arm so I am always ready to raise it to my eye and shoot.
And where my thumb naturally rests is right on top of that damnable Q button.
