The K\u0026amp;F Concept Variable ND Filter ND2-400 72mm reduces the light reaching your lens across a variable range, giving you more room to choose the exposure you want. It’s useful for photographers who want motion blur in daylight, and for video makers who need to manage exposure in changing light. For a flowing-water photograph, choose a slower shutter speed and adjust the filter’s light reduction until the exposure works for the scene. For video, set the shutter and aperture you intend to use, then adjust the filter to bring the brightness under control. The 72mm size is for lenses that take 72mm filters, so it’s worth matching that measurement to your lens before buying. This filter’s main appeal is the combination of variable light reduction and a clearly stated filter size.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eThe K\u0026amp;F Concept Variable ND Filter ND2-400 72mm is best for controlling exposure in bright conditions without changing your chosen shutter speed or aperture. Its ND2-400 range gives you variable light reduction, which is handy when you’re moving between open shade and direct sun or shaping a longer exposure for water. For that soft, blurred-water look, pick the shutter speed for the movement you want, then adjust the filter until the exposure is right. The 72mm size makes the key fit detail straightforward: it suits a lens designed for 72mm filters. One practical limit: the filter reduces light, but it won’t create motion blur by itself; your shutter speed does that.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: K\u0026amp;F Concept\u003c\/li\u003e\n\u003cli\u003eFilter type: Variable ND\u003c\/li\u003e\n\u003cli\u003eND range: ND2-400\u003c\/li\u003e\n\u003cli\u003eSize: 72mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026F Concept","offers":[{"title":"Default Title","offer_id":57492109033812,"sku":"KF-01.1112","price":19.34,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-01.1112_01.jpg?v=1791544458","url":"https:\/\/www.htf-store.com\/it\/products\/k-f-concept-variable-nd-filter-nd2-400-72mm","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
