I have a heavy telephoto lens attached to my DSLR camera. I want to attach the camera strap in such a way so as to be comfortable, but to take the weight of the lens off of the camera lens mount. Therefore, would it be preferable to attach both ends of the strap to the foot of the lens collar? Or one of the ends to the foot of the lens collar & the other end to the camera body? I would appreciate your thoughts if this is something you have sorted out. Thank you so much.
