Just added a 6D to my 7D (both M ii's) and followed some recommendations to look for tutorials on YouTube to figure out some of the different features on my new camera. Nearly every one assumed that this was my first camera ever. So are there videos out there that assume I know that Tv affects my DOF and shutter speed lets me freeze motion and goes directly to things that will be more useful to a non-beginner? I swear, one more mention of "this is the shutter button" and I will not be responsible for my reaction.
