The Quick Release option has little buckles that snap apart to take the strap off.
I attach the buckles so that when you take the strap off you can snap what’s left on your camera together and use it like a handle. It's just a matter of personnel preference which one.
Very convenient if you prefer to take your strap off when using a tripod.
The standard ones are just like what came on your stock strap and attach directly to your camera lugs.
