That gives you room to adjust exposure as daylight changes, rather than choosing one strength before you frame the shot. It suits photographers and video makers who want more control in bright conditions, especially when they’re aiming for a slower shutter speed to show movement or a wider aperture for shallow depth of field. The 49mm size identifies the filter’s fitting diameter, so it’s intended for a lens with a matching 49mm filter thread. This is a focused tool rather than a general protective filter: choose it when reducing incoming light is the job, and leave it off when you don’t need that effect.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eFor photographers framing moving water, drifting clouds or bright outdoor scenes, this variable ND gives you a way to work with changing light without carrying several fixed strengths. Its ND2-400 range lets you make a modest adjustment in softer light or a much stronger reduction in sunshine. I’d change the setting while watching exposure, then settle on the amount that gives you the shutter speed you want. For water, that can help you use a slower shutter to blur the movement; for video, it can help you keep a wider aperture in bright conditions. One practical check: the 49mm diameter needs to match your lens’s filter thread. At the strongest setting, take a fresh exposure reading rather than relying on the one you made before adjusting the filter.\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: ND2-400\u003c\/li\u003e\n\u003cli\u003eSeries: Nano X\u003c\/li\u003e\n\u003cli\u003eFilter diameter: 49mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026F Concept","offers":[{"title":"Default Title","offer_id":57546742006100,"sku":"KF-01.1458","price":39.33,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-01.1458_01.jpg?v=1791716300","url":"https:\/\/www.htf-store.com\/ar\/products\/k-f-concept-variabel-nd-filter-nd2-400-nano-x-49mm","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
