This is the Greenbull camera slider/dolly, model BX200. I purchased it new a year and a half ago and used it four times, but I'm selling it because I sold my camera. This is a professional-grade slider perfect for those who use cinema cameras, DSLRs, or mirrorless cameras with rigs. I was a little worried because it's a Chinese brand when I bought it, but it's easy to use, moves smoothly, and is easy to carry, so I recommend it for those who use it for work. I used this for work at a video production company. Specifications: * Brand/Model: Greenbull BX200 * Load Capacity: 50kg * Rail Length: Approximately 2m (It's an assembly type with three 66cm rails. You can use it from one rail.) * Head: 75mm and 100mm heads can be used as is. * Case: Hard case with rollers I purchased it through personal import from AliExpress in China. It cost about 150,000 yen. * The tripod head and camera in the photos are not included. * There are minor scratches that occur with normal use. Please understand this beforehand. Please refrain from purchasing if you are sensitive to this.
