The BL-D90G L-Bracket is a custom fit for the Nikon D90 Digital SLR Camera body with the MB-D80 battery grip attached. It is a one-piece bracket machined from light weight 6061T6 aluminium that allows full access to all switches & battery drawers when attached to the camera. In the words of a professional landscape photographer, it allows for fast changes from horizontal to vertical composition & vice versa without having to adjust your tripod and/or tripod head, while maintaining lens & viewfinder to eye-level relationship. The Kirk BL-D90G L-Bracket also helps protect the camera body like a truck grill guard & keeps the weight of lens & body over the tripods centre of gravity.
