|If you are looking for a quick way to adjust the focus on your lens, a focusing lever is a great add on. Essentially the bracket gives you a mechanical advantage and an easily accessible point to adjust the focus ring.
This particular bracket is machined from one solid piece of aluminum and then cut to feature a clamp for securing purposes. It can be easily installed and removed just by slipping the bracket over the housing and tightening the screw.
Depending on the lens and scale of your project, the bracket may have a different design and mounting system.
