heres my heath robinson set up ,the long arca plate for tripod or monopod fitting cost all of £4.50 from e.bay ,extra hole drilled for leash £0 .two sets of optech leashes about £10 .its noiseless .it works ,its easily replaceable its extremely easy to unclip to either use in a hide or on a trip/mono-pod and will work with ANY over the shoulder type strap with the long oblong metal slider .. i did try the optech sling strap with it to cut out the metal part but i'm to large to wear it comfortably .as with everything its just a idea that works might suit some not others .View attachment 103126View attachment 103127
I do like that they give you that little attachment point on the side of the tripod collar on those - I have two Peak Design connector thingies either end of a long arca plate attached to my 100-400L, I do find myself longing to move one of them to a different location on the lens for a bit of redundancy.
