Linhof Center Filter, 67mm Graduated Neutral Density Filter for the 58mm f5.6 Wide Angle Lens

• The Linhof Center Filter Balances the Light going through the wide angle lens so that exposure of the negative is even from center to edge.
• Each Graduated Filter is calibrated to one or two lenses.
• There is no set graduation difference such as "1 Stop" or "2 Stop" Difference, the lens determines the density difference between the center of the filter and the edges
