Best Camera Strap You Can Buy"After several years trying different camera straps, from the stock strap that comes with the camera, to other brand straps. The BlackRapid RS-7 comes out as the best I've used.
The fact that you can let the camera hang via it's tripod screw mount on either the camera or lens, distributes the weight very efficiently. Making even the heaviest setup feel light and easy to carry around for extended periods of time.
I would also suggest purchasing the BlackRapid BRAD Underarm Stabilizer strap, this allows you to keep the camera from swinging around when bending down or moving quickly."
