The Kirk BL-50S L-Bracket for the Fujifilm GFX 50S is a custom-made aluminium L-bracket that means that you can change your camera orientation from horizontal to vertical & vice-versa without having to adjust your tripod head. The L-bracket helps to protect the camera body & keeps the combined weight of the lens & body over the tripod's centre of gravity. It is compatible with ' Arca-Type' heads.
