For double the amount of control gained from one 521 series remote, Manfrotto has developed the 521SB Remote Control Splitter Box. The 521SB allows shooters to plug in two 521 series remotes to control the camera with both hands. As an example, users can plug in two 521PRO Remotes, using the zoom wheel on one remote to control zoom in/out and the zoom wheel on the other to control focus in/out. The 521SB is threaded with a 3/8" and 1/4" socket and is supplied with a thumbscrew to easily attach the splitter to a number of mounts including the new Manfrotto FIG RIG camera support system |
