This filter is a combination 6-Stop ND filter and CPL filter. On the NiSi S5 Filter system the CPL filters are rotated using one or both of the adjustment wheels on the side of the filter. This allows you to easily dial-in the strength of the polarizing effect on your scene. As can be seen in the images below there is very minimal color cast on the scene with the CPL rotated to minimal or no effect. The very slight warm cast may actually just be the impact of the exposure time difference and not necessarily a color cast. But even if this is the result of less than pure neutrality it is certainly not bad compared to other ND filters I’ve tested on other lenses. One other observation is that the NiSi Pro IR ND64&CPL Filter with minimal to no polarization effect results in a 6-Stop exposure difference and this remains the same even with more polarization strength dialed-in. nterestingly, It does not appear to increase the ND strength with a stronger polarizing effect.

So it appears that the impact of the CPL’s polarization strength has little to no impact on the 6-Stop ND effect. Interestingly, It does not appear to increase the ND strength with a stronger polarizing effect.
