It suits photographers and video makers who want to manage reflections and the amount of light reaching the lens with the same filter. The CPL function can help reduce glare from reflective surfaces and adjust the appearance of a blue sky; the variable ND range lets you cut light when you want a slower shutter speed or a wider aperture in bright conditions. That makes it particularly relevant for scenes with water, glass or strong daylight, where reflections or exposure can get in the way of the result you want. The ND2–ND32 range gives you adjustable light reduction rather than one fixed level. It’s a practical combination for a lens with a 52mm filter thread, especially when you want to balance two different kinds of control without carrying separate filters.\u003c\/p\u003e\n\u003ch3\u003eUsing the combined filter\u003c\/h3\u003e\n\u003cp\u003eThink of its two functions as separate adjustments for different problems. Use the polarising effect to manage reflections or sky contrast, then use the variable ND setting to control exposure. The filter can help keep video shutter choices or longer-exposure effects workable in brighter light, while the CPL addresses glare that an ND filter alone doesn’t remove. Results from polarisation depend on the scene and your shooting angle, so it’s a considered adjustment rather than a uniform effect across every frame.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eThe K\u0026amp;F Concept CPL + Variable ND Filter ND2-ND32 Nano X 52mm is best at combining reflection control with adjustable light reduction. I’d consider it for bright-day video or a softer rendering of moving water: at ND32, the light reduction is 32-fold, so a 1\/60-second exposure can become roughly 1\/2 second if the other exposure settings stay the same. Its 52mm size means it’s for a lens with a matching 52mm filter thread, so it won’t suit a different thread size directly. The polarising effect also depends on your angle to the light; I’d adjust it for the scene rather than expect the same result in every direction.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: K\u0026amp;F Concept\u003c\/li\u003e\n\u003cli\u003eFilter type: CPL and variable ND\u003c\/li\u003e\n\u003cli\u003eND range: ND2–ND32\u003c\/li\u003e\n\u003cli\u003eFilter size: 52mm\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":57492118765908,"sku":"KF-01.1377","price":47.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/KF-01.1377_01.jpg?v=1791544477","url":"https:\/\/www.htf-store.com\/it\/products\/k-f-concept-cpl-variable-nd-filter-nd2-nd32-nano-x-52mm","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
