Decent coatings and color rendition. No noticeable color cast.

Der ND8 Filter erfüllt seinen Zweck und verdunkelt das Bild leicht. Dies ermöglicht längere Belichtungszeiten.
Leider kommt der Filter in einer Dose die für verschiedene Filterdurchmesser gedacht ist. Diese nimmt daher mehr Platz als nötig weg und macht das versorgen des Filters nicht in jeder Situation einfach.
