Do you ever carry two cameras on a shoot? If you do then you know the trouble that comes with this territory. Two cameras on their original camera straps are prone to clank into each other and weigh your neck down. It is uncomfortable to say the least, is not good for your camera bodies or lenses, and just is not an efficient way to work.
I shoot a lot of baseball games and like to have two camera bodies on me. My main camera, the Nikon D300, sports the 70-200mm f/2.8 lens and is mounted on a monopod. The second camera is my older Nikon D-70 with the 24-70mm f/2.8 lens. I really like this combination but carrying the second camera on its regular strap was becoming nothing short of a pain in the neck!
I heard about the R-Strap and decided to give it a try since I also had a wedding coming up. I tried it and I love it!
You can read my review of the R-Strap that I posted on my website. If you ever carry two camera bodies you really should consider using the R-Strap.
