The Sigma RS-31 Remote Controller allows the photographer to take self-portraits or get into group shots. When used in conjunction with the Mirror Lock-Up function, it can reduce the possibility of image-blurring caused by camera shake, making it particularly useful for macro or telephoto shooting.
