Admittedly, my method of attaching the camera to the BlackRapid Strap
makes vertical shooting a bit uncomfortable (but not prohibitively so). This product looks like an interesting solution to the problem. [Sean]
The CAMS Pro line of a products is a revolutionary way to carry, shoot, and mount your pro bodied or gripped camera and telephoto lens.
Carry And Mount System started off with the simple goal of mating a bottom-mounted sling strap to a camera in a way that would not interfere with using a vertical shooting grip. We did not set out to develop a plate that was Arca-compatible and made the vertical grip more comfortable to use, but when we mounted the first machined prototypes, we found that we had surpassed our original intent by far. Fortunately, we did not stop there. Involving other photographers led us to rethinking the strap and strap connection and adding the threaded insert (which seems so obvious now). Using hindsight to our advantage, the lens plate evolved quickly into a natural companion of the camera plate, as essential to the system as the telephoto lens is to the photographer.
Each component of CAMS is designed to offer the perfect balance of comfort, convenience, and strength.
