That flexibility is useful when you want to keep a particular shutter speed or aperture as daylight shifts. This K\u0026amp;F Concept filter suits photographers and video makers who work outdoors and want room to adjust exposure without changing filters. Its magnetic design makes quick fitting and removal part of the appeal, while the 49mm size keeps it specific to setups that use that filter size. The Nano X name identifies the product line; the facts available here don’t support claims about particular coatings or optical performance, so I’d focus on what the title confirms: a variable ND filter with a magnetic fitting and a stated ND8-128 range. It’s a practical tool for managing bright scenes, provided the filter size matches your lens setup.\u003c\/p\u003e\n\u003ch3\u003eWorking with variable ND\u003c\/h3\u003e\n\u003cp\u003eUse the filter when you need to hold a slower shutter speed in bright light, for example to give moving water a softer appearance, or when recording video and want to keep your chosen shutter setting. The amount of reduction you need depends on the scene and your exposure settings. A variable range gives you room to adjust rather than committing to one ND strength, but it doesn’t remove the need to check exposure as the light changes.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eAt midday by a bright canal, this is the sort of filter that can make a deliberate slow-water exposure possible without waiting for softer light. The ND8-128 range gives you varying levels of light reduction, so you can set a target such as 1\/4 sec and adjust exposure for the scene rather than settling for a faster shutter. Its magnetic fitting is handy when clouds move across the sun and you need to take the filter off quickly. I’d point this out to someone filming outdoors too, especially if they want to keep a chosen shutter speed. Just make sure the 49mm size suits the lens setup you plan to use.\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: ND8-128\u003c\/li\u003e\n\u003cli\u003eSeries: Nano X\u003c\/li\u003e\n\u003cli\u003eFitting: Magnetic\u003c\/li\u003e\n\u003cli\u003eSize: 49mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026F Concept","offers":[{"title":"Default Title","offer_id":57512773222740,"sku":"KF-01.1973","price":61.23,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-01.1973_01.jpg?v=1791588275","url":"https:\/\/www.htf-store.com\/de\/products\/k-f-concept-variable-nd-filter-nd8-128-nano-x-magnetic-49mm","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
