The JJC S-NX Camera Remote Shutter Cord is a compact wired remote control for Samsung cameras. The cable is designed to prevent camera shake during super telephoto zoom, macro photography and bulb shooting. It is useful for taking pictures of subjects that are difficult to approach or to minimise vibrations during close-ups and long exposure shots. The JJC S-NX works like the normal shutter release button, with half or full pressure, and also has a shutter release button for bulb exposure.
