In days far past, when a photographer wanted to move a tripod mounted camera from landscape to portrait orientation, he or she would flip the camera to one side or another using capabilities present in most tripod heads. But flipping a camera using a tripod-mounted head can sometimes take precious time. It also means that the camera is no longer perfectly balanced on the top of the tripod causing the head to take more of the camera weight than is necessary. Also, depending on the size of the camera and the tripod being used, some photographers may find it difficult to achieve perfect 90-degree positioning. Finally, the photographer will likely need to recompose the scene after flipping the camera. Although you may think this particular problem is a trivial matter, reorienting a camera makes a big difference when taking photographs in the field under rapidly changing lighting conditions; every second counts.
With an L-bracket, photographers can change a camera’s orientation by removing camera from the tripod and remounting it on its opposite axis; no adjustments are required on the tripod head itself. This is accomplished using an L shaped Arca-Swiss style quick release plate, commonly referred to as an L-bracket.
There are many different brands of L-brackets available on the market today including products by Manfrotto and several generic import brands. However, most professional photographers agree that two of the best L-brackets are manufactured by Really Right Stuff (RRS) and Kirk Enterprises. With my recent purchase of a second Nikon D2x camera body, I felt it was a good time to compare the L-brackets provided by these two major superpowers of mounting technology.
