Density is set by rotating the filter's silver control knob, and the transition through the range is smooth and continuous — so you can dial in exactly the exposure you need instead of swapping fixed ND filters.\u003c\/p\u003e\n\u003cp\u003eFor video and cinema work, where shutter angle and frame rate are fixed, a variable ND is what lets you keep a wide aperture and shallow depth of field in bright light. For stills, it opens up long-exposure techniques like blurring water or moving crowds in daylight.\u003c\/p\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.5–5 stop variable density\u003c\/strong\u003e — continuous adjustment across the full range from a single filter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilver control knob\u003c\/strong\u003e — easy, precise rotation of the front element, even with gloves or a lens hood nearby.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e49mm mounting thread\u003c\/strong\u003e — screws directly onto any 49mm filter thread.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversized front thread\u003c\/strong\u003e — the front of the filter is stepped up beyond 49mm to help avoid vignetting on wider lenses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePro Nano coating\u003c\/strong\u003e — multi-layer nano coating adds water- and oil-repellent, anti-reflective protection to reduce ghosting and flare.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptical glass with an aluminum frame\u003c\/strong\u003e — keeps the filter rigid without adding meaningful weight to the front of the lens.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e NiSi recommends variable ND filters on focal lengths of 35mm and longer.
