Remember that if you intend to attach to the tripod socket, the manufacturer probably did not design the socket to withstand forces generated by the camera's weight being swung at the end of a pendulum. Using a strap on a strap lug may be safer, but again, if you're using one of two lugs then you're doubling the weight it may have been designed to support. I personally always prefer a neckstrap attached to both lugs. (Yes, some lightweight cameras may only use one lug, like a Rollei 35, but then again that's the way it was designed.)
