Camera stabilizer is a device which is purposely designed to hold the camera in such a manner that it prevents camera shakes. Camera stabilizers are generally hand held but can be used in number of ways. They can be used with arm support brace and body support system. The main purpose of camera stabilizer is to hold the camera and prevent unwanted camera movements resulting in stable, steady and smooth shots. If you are using camera stabilizer with a body support system, they are extremely comfortable and you can carry them for long hours of shooting.
Any High End DSLR or Mid Range DSLR Camera comes with HD support , You should be clear about your objective as to why you need HD support.
