On a workshop with Chas Glatzer, Chas told us about a solution to add an additional degree of safety to your camera, big lens and tripod that I thought I would pass along. It calls for combinations of two or three straps depending on what camera and lens combination you are using and want to secure.
First, you attach a strap with a rapid release clip to the lens. The strap is a Kevlar web strap that attaches to the strap lugs on the big lenses that are normally used for carrying straps. Remove the carrying strap and attach one of the release straps below. I attach only one and to the left side. http://www.upstrap-pro.com/product/XPS-QR/SG-XX-QR-E-K.html is the link to order. Two come in a package so I attach them to all of the big lenses that have the strap lug.
Next I attach the black wrist loop with the large rapid release clip to my tripod. So instead of putting the loop around my wrist, I put the loop around the tripod head and then cinch it tight. http://www.upstrap-pro.com/product/XPS-QR/SG-XX-LOOP.html. I leave this strap on my tripod always.
Now to quickly add an additional level of security, simply snap the rapid release clips on both lens and your done.
Now what about the camera itself? Chas uses a carabiner clip with a loop such as the one below to attach to the camera. The carabiner clips around the strap looped around the tripod. http://www.sonic-uk.com/product_details.php?prodid=101….I is one place to order such a strap. UPstrap makes a camera side strap with a rapid release clip but you only have one release clip coming off your tripod. It would be handy however if you are shooting a lens with out a strap lug and your only option is securing the camera.
