This ProMediaGear bracket plate is custom-fitted for Sony Alpha A7 IV. The bracket plate can be mounted to ProMediaGear flash brackets or L-Brackets. Since it is custom designed it fits like a glove perfectly matching the camera shape, it also provides anti-rotation so the plate won't slip or twist. The plate has been machined from solid Aluminum T6061 block and has a hard black anodized surface coating for a scratch-resistant finish. The plate also features 1/4-20 threads for mounting other quick-release plates or accessories.
