Features
- The CBF1 neutral density filter is used primarily to make a proper back focus
adjustment when installing motorized zoom/ auto-iris lenses. To assure that a zoom lens
stays in focus through the entire aperture range, the camera must be back-focus when
the lens iris is wide open. The CBF1 filter is placed in front of the lens to keep the
auto-iris open during adjustment. This unit is an essential tool for the professional installer!
