Tripod UC-04 tube clamp & Arca-Swiss fast coupling

The UC-04 clamp can be attached to the side of your L-plate using the Arca-Swiss connector. Then it is possible to clamp an accessory with the swivel jaw. A good example is the use of an umbrella. On one side you clamp on the L-plate, on the other side you clamp the rod of a handy folding umbrella in the holder. This way you place the screen over your camera so it stays dry and you have your hands free to operate the camera.
