This is a variable neutral density filter, so you can adjust how much light reaches the camera rather than choosing from a set of fixed ND filters. Its ND8-128 range corresponds to roughly 3 to 7 stops of light reduction. That makes it useful when you want a slower shutter speed in bright conditions, or need more control over exposure while keeping your chosen aperture. It suits photographers and filmmakers using a lens with a 55mm filter diameter who want ND control in a compact, changeable setup. For example, reducing light can help render moving water with more blur or make a slower video shutter practical outdoors. The range gives you room to adjust, though the filter is specifically sized for 55mm lenses.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eThe magnetic fitting makes adding or removing this filter a simpler part of setting up, rather than another filter to screw on and off. I’d point it out to someone who often changes between filtered and unfiltered shooting, especially outdoors where light can shift. The ND8-128 range gives you about 3 to 7 stops to work with: if your exposure is 1\/125 sec, ND128 can bring that to about 1 sec at the same aperture and ISO, which is useful for softening moving water. The 55mm size is the key practical limit; it’s for lenses with that filter diameter, not a universal fit. For those lenses, it’s a handy way to vary light reduction without carrying several fixed ND strengths.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFilter type: Variable ND\u003c\/li\u003e\n\u003cli\u003eND range: ND8-128\u003c\/li\u003e\n\u003cli\u003eAttachment: Magnetic\u003c\/li\u003e\n\u003cli\u003eSize: 55mm\u003c\/li\u003e\n\u003cli\u003eSeries: Nano X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026F Concept","offers":[{"title":"Default Title","offer_id":57512773845332,"sku":"KF-01.1975","price":64.42,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-01.1975_01.jpg?v=1791588277","url":"https:\/\/www.htf-store.com\/es\/products\/k-f-concept-variable-nd-filter-nd8-128-nano-x-magnetic-55mm","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
