Kenko 40.5mm Real Pro Circular Polarising Filter

The Kenko 40.5mm RealPro Circular Polarising Filter is designed to give professional grade results. Treated with a water resistant anti stain coating, the filter is easy to clean and long lasting. It delivers maximum light transmission with minimal reflections, and its ultra thin frame prevents vignetting effects even when used with super wide angle lenses. The frame is also designed with a knurling edge for a secure grip, meaning the filter won't slip out of the hand.
