I have just got my hands on a secondhand 7DmkII and my initial impression is good, however one thing is troubling me and I am trying to work out if it is just the way it is or something odd on this camera. On other cameras (when not using back button focusing) if I half depress the shutter button it will AF and meter and then when I fully depress the button it will fire. With the 7DmkII the button is extremely sensitive and it is basically impossible to get it to AF and not shoot. I have been trawling through the settings in case this is an issue (but did a full reset when I got the camera so i assume it isn't that). Is this how they are or is this just an oddity of the one I have bought?
