H&Y shows off its new magnetic fix for cross-polarization in Revoring variable ND

Filter manufacturer H&Y has launched a series of magnetic ND filters that it says are designed to eliminate cross-polarization effects in its 1.5-10 stop variable ND Revoring when used with wide angle lenses. The idea is to couple the new magnetic ND filters with the VND of the Revoring adding the two filters together so that the VND can be used at a lower strength where the X effect doesn't occur. The new clip-on ND filters come in ND4, 8, 16 and 400 strengths which can combine with the ND3-100...
