It suits photographers who want to show movement in a scene, such as smoothing flowing water or giving clouds a gentle blur, while keeping their chosen aperture and ISO. The ND 2.1 rating describes the same strength in another way; it cuts the light reaching the camera by seven stops. That can turn a shutter speed of 1\/125 sec into roughly 1 sec, a practical starting point for a long exposure. Its 72mm size is for a lens with a matching filter thread, so it’s important that the diameter matches the lens you plan to use. This is a focused tool for controlling exposure, rather than a filter for changing colour or adding effects.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eSeven stops means you can make a daytime exposure last around a second instead of 1\/125 sec, which is enough to soften the movement of a stream while keeping the camera still on a tripod. I’d consider this one when you want that deliberate blur but don’t want to close the aperture just to lengthen the exposure. The 72mm diameter matters at the point of fitting: it suits a lens whose filter thread is 72mm, so match that measurement before planning a setup. It’s a strong reduction, and for less dramatic movement or a shorter exposure, you may need a weaker ND filter instead.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFilter type: ND filter\u003c\/li\u003e\n\u003cli\u003eFilter diameter: 72mm\u003c\/li\u003e\n\u003cli\u003eOptical density: ND 2.1\u003c\/li\u003e\n\u003cli\u003eLight reduction: 7 stops\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Formatt Hitech","offers":[{"title":"Default Title","offer_id":57563703869780,"sku":"FH-FC72ND2.1","price":81.28,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.htf-store.com\/nl\/products\/formatt-hitech-firecrest-nd-72mm-nd-2-1-7stops-filter","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
