This dedicated L-bracket has been designed to perfectly fit the Sony Alpha A7 IV camera, and will also work** with the A7R V, A7 III, A7R III, A7R IV, A7S II, A7S III, A9 II and A1 camera bodies. ALFIE is a standard 38mm Arca-Swiss compatible L-bracket and is made from aerospace-grade magnesium alloy. This L-bracket gives users access to the battery door and side ports on all cameras. The cut-out in the vertical aspect allows rear screens to be opened either upright or tilted, and Alfie also has two 1/4"-20 threads for attachment of accessories. The base extends to enable tethering in portrait orientation and there will be a cable management tool included in the box to help support cables when plugged into the side of the camera. 3 Legged Thing have supplied a Peak Design v3 Capture compatible adapter in the box to allow users to use ALFIE with their v3 Capture clip. **Other models may vary with access to screen movement and cable door access. Manfrotto tripod owners: all of our L-brackets are standard 38 mm / 1.5" Arca-Swiss compatible. Manfrotto Arca-Swiss heads may have a lipped clamp that will prevent L-bracket use. Manfrotto RC2 plate heads are not compatible. Please check your head model before ordering.
