Many of us have way more experience than the layman. What are your experiences in trying to get yourself into shots with your fancy equipment? Yes, that's what other people call your big bad boy, believe it or not. For example: group shots or just some snaps with you and the background while traveling.
Do you let family/friends/strangers use your camera? Do you give him/her a quick guide? Left hand on lens, not body? Mode dial on P? Preset your focus point? Hear a complaint about the camera not being on? Turn on live view or explain the viewfinder? Make sure he/she has the strap round the neck? Tuck their elbows? Coach a designated family/friend shooter ahead of the trip?
