The Formatt Hitech Firecrest ND 49mm ND 2.4 Filter reduces the light entering the lens by eight stops, so you can extend exposure without changing the scene or your framing. It suits photographers aiming for deliberate motion blur, or those who want to use a wider aperture outdoors in strong light. Think landscapes, rivers and outdoor portraits where you’d like a shallower depth of field. The 49mm size is for a lens with a matching filter thread; it isn’t a camera-mount specification. Eight stops is a substantial reduction, so this filter is most useful when normal exposure settings leave too much light for the shutter speed or aperture you want.\u003c\/p\u003e\n\n\u003ch3\u003ePlanning the exposure\u003c\/h3\u003e\n\u003cp\u003eThis is a fixed, strong reduction in light, so decide what you want the shutter speed or aperture to do before setting the rest of the exposure. As a simple example, an unfiltered reading of 1\/125 sec becomes about 2 seconds after eight stops. That can blur moving water while keeping stationary rocks or riverbanks defined. People and leaves in motion will blur too, so take that into account when choosing your composition.\u003c\/p\u003e\n\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eEight stops leaves about one 256th of the original light, which gives you meaningful room to slow the shutter or open the aperture in bright conditions. The ND 2.4 rating expresses that same strong reduction as optical density; I’d consider it for smoothing moving water or managing bright outdoor light when you want a wider aperture. Its 49mm size means the lens needs a matching 49mm filter thread, so match that marking on the lens. This is a strong filter rather than a subtle exposure tweak. If you only need a small adjustment, eight stops may be more than you want.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFilter size: 49mm\u003c\/li\u003e\n\u003cli\u003eND density: 2.4\u003c\/li\u003e\n\u003cli\u003eLight reduction: 8 stops\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Formatt Hitech","offers":[{"title":"Default Title","offer_id":57563709899092,"sku":"FH-FC49ND2.4","price":65.08,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.htf-store.com\/it\/products\/formatt-hitech-firecrest-nd-49mm-nd-2-4-8stops-filter","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
