I’ve been shooting photographs for years and the common neck strap has always given me nothing but neck pain. My father though he had found a solution with a neoprene neck strap, but eventually it had the same shortcomings as its predecessor.
One day, while attending a convention, a friend pulled a Black Rapid strap out of his bag. Within an hour I had found and purchased one for myself. The strap slips easily over one shoulder and allows your camera to hang comfortably at your side with no strain on your neck.
The camera attaches to the strap through a custom tripod mount and a carabiner connecting kit that allows the camera to be brought up to shooting position without having to shift the strap (the metal connection slides across the fabric strap). This makes it easy to swing your camera up and shoot in a simple fluid motion, and return the camera back down to your side the same way. Another benefit of this connection method is that it reduces strain on the camera body when shooting with large lenses that have tripod collars.
The straps are sturdy, well built and come in a variety of sizes and styles including the RS-DR-1 which can hold two SLRs at once, although that’s really more for the professional photographer.
