It’s made for photographers and video makers who want more control over shutter speed or aperture in bright conditions. For a portrait outdoors, reduce the incoming light to keep the aperture you want; for moving water, use the filter to allow a longer shutter speed and capture more motion blur. The variable range makes it practical when light changes and you’d rather make a quick adjustment than stop to replace a fixed-strength filter. Its 77mm size is relevant when choosing a filter for a lens with a matching filter thread. This is a focused tool for controlling light, not a UV filter: its purpose is to reduce exposure. At the strongest settings, take care to check your exposure as you adjust.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eChanging the light level is a quick adjustment with a variable ND, which can keep a bright scene from dictating your shutter speed or aperture. I’d point this out to someone filming outdoors, or photographing a stream and wanting the water to blur: set the aperture or shutter speed for the look you’re after, then adjust the filter to bring exposure back under control. The ND2–400 range gives you room to work from modest reduction to a much darker setting. The 77mm size is the detail to match against your lens’s filter thread before choosing it. At the heavier end, exposure deserves a fresh check; this isn’t a set-and-forget filter.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: Variable ND filter\u003c\/li\u003e\n\u003cli\u003eND range: ND2–400\u003c\/li\u003e\n\u003cli\u003eSeries: Nano X\u003c\/li\u003e\n\u003cli\u003eSize: 77mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026F Concept","offers":[{"title":"Default Title","offer_id":57546745184596,"sku":"KF-01.1465","price":55.4,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-01.1465_01.jpg?v=1791716303","url":"https:\/\/www.htf-store.com\/es\/products\/k-f-concept-variabel-nd-filter-nd2-400-nano-x-77mm","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
