NiSi HUC PRO Nano IR ND64 + CPL 82mm Multifunctional Filter – When shooting long exposure adding ND and a CPL together is a must, you can control reflections and also the shutter speed. But with screw-in filters is a pain, but it’s much easier if you have an integrated CPL: you don’t need to stack CPL on top of ND filters anymore, don’t add more glass in front of your lens and get the most out of one filter. With stunning performance in sharpness and no-colour cast. The NiSi PRO Nano IR ND64+CPL has all the top feature of NiSi Filters: IR Coating, Nano Coating, SCHOTT Optical Glass, SLIM frame and a top performance CPL.
