The filter uses Japanese optical glass and a 12-layer multi-coating to minimize color cast, though slight shifts can occur in extreme settings; tests show it is generally neutral.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the slim profile prevent vignetting?\u003c\/strong\u003e\u003cbr\u003eAnswer. The 6mm ultra slim design reduces vignetting for wider angles, and the larger front 72mm thread further helps avoid edge darkening with many wide lenses.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do you lock the filter position?\u003c\/strong\u003e\u003cbr\u003eAnswer.
