With about twice the correcting effect of the KB1.5 (82A) filter, the 52mm B&W KB3 Cooling Color Conversion Slim Glass filter removes the orange-red color cast that appears on photographs made on tungsten reversal film with artificial lights using 100-200 Watt bulbs, or from aged photoflood lamps. Therefore, this filter is ideal for neutral color reproduction with appropriate illumination.
B&W slim filters are for wide-angle lenses and are 3mm thick. They do not have a front thread.
