This Vello Bluetooth ShutterBoss Advanced Intervalometer Kit from B&H contains four remote shutter cables which allow the included receiver to work with most Nikon cameras that can accommodate a wired remote shutter release, as well as with select Sony or Minolta cameras. Once connected, this intervalometer kit allows you to control a camera from a compatible iOS smart device. In addition to the intervalometer mode, you can also trigger the shutter in single shot mode, continuous mode, bulb mode, or self-timer mode.
