This is the Wooden Camera Unified DSLR 15mm Baseplate. This is a high-quality baseplate made in the USA, known for its precision and strength. Retail price: 42,350 yen. It's a 15mm LWS standard, ARRI dovetail plate specification, offering high versatility and expandability for rigging with some ingenuity. I purchased it but never used it, so it's in near-new condition, having only been opened and handled briefly to check its build quality. If you're looking for a high-precision baseplate for video shooting with a mirrorless camera or similar, please consider this.
