The SHAPE C300 Baseplate is made specifically for the Canon EOS C100 C300 C500 cameras. This camera accessory provides a small, light setup solution expandable to a more elaborate setup. It features a pair of 15 mm rods that are 12″ long through the length of the baseplate. The baseplate attaches underneath the camera with 4 x M4 screws or with 3/8”-16 and 1/4”-20 screws that are included. The baseplate maintains the proper lens center to the rod height for use with available rod mounted accessories. This allows you to use available standard follow focus units, zoom motors, and matte boxes with your camera while using the baseplate.
