The Chrosziel Matte Box and Baseplate Kit is an expandable studio and shoulder rig for the Sony FS7 camcorder. Included is a 15mm LWS baseplate with 15mm rods, which is height-adjusted and shaped for the FS7, so it can fit properly with the 450W-20 Super-Wide Matte Box. The baseplate also has a built-in shoulder pad for handheld filming, if you choose add handheld shooting accessories in the future. The included Dual Stage matte box includes rubber donut inserts to take a variety of stills and cine lenses. A top flag to prevent ghosting and lens flares is also included with the matte box. To round out the rig, a follow focus is also included along with the appropriate drive gears to use them with standard mod 0.8 lenses. While functional on its own, this rig can serve as a jumping-off point to mounting other optional accessories such as lens supports, motors, and handles, to create your own custom rig that fits your workflow. See below for more information on the individual items.
