Product Overview

MC CPL Series

NISI’s CPL Series of Ultra Thin Filter adopts a special thin-film gluing technology and the newest high quality Japanese Polaroid film. Its double side, anti-reflection multi-coating technology can effectively enhance transmittance and reduce reflectivity. The edge of lens is all painted with Japanese polishing paint for anti-reflection, which reduces the effect of glare and ill-defined rays on the image. Meanwhile it can eliminate completely the useless light reflection from non-metallic surfaces. High quality lens guarantees CPL filters super smooth finish on the surface. Ultra-thin high quality aluminum frame (thickness only 7.05 mm) with super fine dull polishing and elaborate knurling makes sure that the frame will not blanch because of repeated rotation. This ultra thin filter frame can avoid vignetting on super wide angle lenses. All materials used in this filter meet the requirements of European Union’s standards of environment protection—ROHS(Restrictions on Hazardous Substances), they contain nothing hazardous. The screw thread in front of the frame makes it easy to fix the lens cap and other accessories.
