The accessory kit also contains four products that fulfill your lighting and remote-operation needs. The included Vello Multi-Function Ball Head can mount to the camera's shoe mount and hold a monitor or small light. The Switronix FLEX DSLR remote optically triggers video recording start and stop for a Canon 5D or 7D from up to 3.3' (1m) away. The remote clamps to a tripod handle or other rod with a diameter of 1.5" (3.8cm) or less. The Switronix TL-50 LED compact light fixture emits the equivalent of a 30W light and is dimmable by dial. This mounts to the camera's hot shoe via the included universal shoe adapter, which attaches to one of the light's top and bottom 1/4"-20 thread mounts.
