Color Compensating Filters ( C )

	These filter types selectively absorb in the red and near-infrared wavelength regions and compensates for imaging sensitivity and exposure meter sensitivity. CD5000 features 0.45 mm as standard thickness and spectral characteristics equivalent to other C series with less than half of their thickness.
