The DSLR baseplate is our adjustable and expandable baseplate. It comes with a pair of 3.5" male/female rods in order to mount a follow focus and/or matte box; rod extensions may be necessary for long lenses. The baseplate mounts to your camera using a _ 20" screw. The baseplate has multiple _" 13 threads on all sides; (1) _" 13 thread on both the left and right side, (4) _" 13 threads on the front (2 on the top and 2 on the bottom) and (2) _" 13 threads on the back . The multiple 1/2" 13 threads allow you to mount rods on all sides of the baseplate allowing you to create your perfect rig. You can mount rods off the side to make a shoulder mounted rig or to build a cage. The Allen screws in the front of the baseplate adjust the height of the plate for compatibility with all DSLR cameras with and without battery grips for use with follow focuses and matte boxes.
Your camera can also be quickly released from the rig by turning the red knob then pulling up on your camera. The camera quick release plate stays mounted to your camera so you can quickly switch between using the camera as part of a rig or on its own. You can easily add the optional Z-Finder Pro by attaching the Z-Finder Mounting Frame (included with the Z-Finder Pro) to the camera quick release plate using two thumb screws. Your tripod plate mounts to the bottom of the plate by using the standard tripod screws, (2) 1/4 20" and (1) 3/8 16".
