Originally posted by rawr A cheap and simple alternative two body solution, if I am using a backpack or a Lowepro harness, is to clip a big carabiner onto each shoulder strap of the backpack or harness, and then clip the camera neck strap (shortened if need be) of each camera body onto one of the carabiners. This keeps both cameras at hand, stops them flopping around too much when I move about, and stops them dragging along the ground when I crouch down.
I recommend using 2 carabiners on each side with the openings facing opposite directions (1 away from your body, one towards your body). I might seem stupid, but trust me, you'll know why after you dropped a camera
If i'm not using a backpack, I mostly just hang my second camera diagonally (right shoulder to left hip) and my main camera on my right shoulder. If I need to move quick I tend to lock them together with a carabiner behind my back to make sure none slips away (definitely when using a third camera).
As a side-note, I prefer to use the slim old-school straps or make my own from prusik rope if I want a different lenght
