The Sachtler Ace Base Plate is the ultimate camera baseplate that supports 15-mm rods, and 1/4″-20 and has 3/8″-16 tripod mount threads on the bottom. It is height-adjustable and can be attached to the camera directly. With a payload up to 15.4 lbs it offers flexibility when attaching additional accessories. You are able to attach two 15mm rods- to hold your follow focus or matte box- and secure them both in place with just a flip of one lever. Along with the baseplate you get a quick release plate, anti-twist stop, and spare mounting screws. The anti-twist stop prevents your camera from turning, essentially locking it in place.
