The bottom line: this is a simple, well-made \u003cstrong\u003eneutral density filter\u003c\/strong\u003e that gives exactly 3 stops of light reduction in a standard 4x4 in (100 mm x 100 mm) format, making it useful for matte box and holder workflows where controlling exposure or creating motion blur is required. It is best considered when steady color fidelity and easy slot-in compatibility matter more than exotic coatings or variable ND mechanics.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh quality optical glass:\u003c\/strong\u003e Delivers consistent light transmission and keeps color rendition neutral so photos and footage do not shift hue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eND8 \/ 3 stops:\u003c\/strong\u003e Reduces light by three stops, allowing wider apertures or slower shutter speeds for shallower depth of field and controlled motion blur.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-layer coating:\u003c\/strong\u003e Coatings on both sides reduce reflections and help minimize ghost images when used on lenses and matte boxes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatte box compatible size:\u003c\/strong\u003e The 4x4 in (100 mm x 100 mm) sizing fits common filter trays and holders like Cokin Z, Hitech, and Lee systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThin 2 mm profile:\u003c\/strong\u003e A slim thickness that slides into filter trays easily and keeps stack height low when multiple filters are used.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Fotga ND8 suits independent filmmakers, DSLR and mirrorless shooters, and photo enthusiasts who use a 4x4 in matte box or filter holder and need a dependable, color-neutral way to cut three stops of light.
