The Kirk BL-5 D Mark IIIG L-Bracket, for the Canon EOS 5D MK III digital SLR, is a custom-made one-piece aluminium L-Bracket for the Canon EOS 5D MKIII with the BG-E11 grip attached. When attached it allows full access to all the switches, including full use of the remote control, & battery drawers & allows quick changes from horizontal to vertical composition & vice-versa without having to adjust your tripod and/or tripod head. The Kirk L-Bracket also helps to protect the camera body & keeps the weight of the lens & body over the tripod's centre of gravity. The L-Bracket from Kirk attaches directly to Kirk Ball Heads & other ' Arca-Type' heads.
