The CBF-1 Neutral Density Filter is used primarily to make the proper back focus
adjustments when installing motorized zoom lenses. To assure that a zoom lens
stays in focus throughout the zoom range, the camera must be backfocused when
lens iris is wide open. The CBF-1 is placed in front of the lens to keep the
auto-iris open during adjustment. The filter is 4" x 4" square and made of glass
- not plastic - and has an ND rating of 3.0. The CBF-1 filter is an essential
tool for the professional installer. Protective case included.
