This is a set of a lightweight and durable carbon fiber tripod and head. I believe it has almost never been used to mount a camera or video camera, only opened. I received it from an elderly acquaintance who owns a Leica camera, but I have no opportunity to use it, and the mount is different, so I am putting it up for sale. I apologize, but I have never used it to mount a camera, so I do not know the details of how to use it. - Brand: Manfrotto - Model: 190CX3 - Material: Carbon Fiber - Accessories: Carrying case Head: 391RC2 Thank you for viewing. Since it is also listed on other auctions, I apologize if it is sold first. Since it is not new, please be sure to check the condition in the photos and only purchase if you understand and agree.
