A simple, no-tools device for improving balance issues when using a lightweight camera with a heavier telephoto lens.

In general, a small DSLR body (such as the Sony 6xxx series, Canon 7D/6D or Nikon D7x00) have improved materials and lower weight, making it tricky to balance with older heavier telephotos. Rather than trying to use a longer lensplate (which may restrict your tilt angle) you can use a Jobu Hockey Puck, which adds 5oz (140g) to your camera, allowing you to push the balance forward.
