K&F CONCEPT CPL Filter Kit for Mobile, Magnetic 49mm Nano-K Series

DIRECT-FIT THREE-LENS MODULE BASE: Designed exclusively for iPhone 17 16 15 14 Pro and Pro Max, this custom three-hole dock attaches directly to the camera's Deco module. With a secure clamping force of 4N to 20N, it completely eliminates the three major flaws of traditional filter clips: sliding, screen lock and clogging the Mag‑Safe area, leaving the rear completely free for gimbals or wireless chargers. 49mm CPL WITH ROTATABLE POLARISATION: Includes a 49mm multi-coated circular polarizer with aluminum alloy frame that fits into the base using physical alignment guides. Once assembled, the filter can rotate freely within the slot, allowing you to precisely adjust the polarization angle to effectively eliminate reflections from water and glass, improve contrast and enrich natural colors. 15G ULTRA-LIGHTWEIGHT PROFILE: With a compact base of only 41×38×4.16mm and a total kit weight of about 15g (well below 20g), this configuration offers an almost imperceptible, pocket-sized carrying experience. It adds virtually no weight to the phone, ensuring optimal balance and stability when using handheld motorized gimbals or tripods, without affecting daily operations. IPHONE 17 PRO SERIES CASE COMPATIBLE: Designed with the convenience of using iPhone 17 Pro and Pro Max case in mind. The base is fully compatible with official Apple cases and with large or volcanic window cases (with a camera module thickness ≤ 14 mm). DUAL-LOCK STABILITY: Built for maximum reliability, the base integrates two pre-embedded high-specification neodymium magnets on the B-side, along with a physical snap lock mechanism that secures the filter against accidental drops. Fiber-reinforced nylon base maintains stable tension without loosening or scratching the phone lens.
