The K&F 58mm Screw-In iPhone Magsafe Double-Sided Magnetic Filter Holder for iPhone 17 Pro Max provides a precision fit, strong double-sided magnets, and supports 58mm filters including the included VND filter. It ensures stable, secure, and versatile mobile photography with comprehensive protection and portable storage.

Upgrade your iPhone 17 Pro Max photography with the K&F 58mm Screw-In Magsafe Double-Sided Magnetic Filter Holder. Custom-engineered for the iPhone 17 Pro Max, its triangular lens cutout and rectangular Deco opening align perfectly with the lens module, flash, and antennas, preventing light leakage and signal interference while keeping the camera fully functional.

The double-sided magnetic mount features 17 strong N52-grade neodymium magnets on the front and 8 on the back, providing 2500gs (≈8N) of magnetic pull for quick and stable attachment. It also supports magnetic accessories such as fill lights and tripods for versatile use.

Included is a VND (Variable Neutral Density) filter made of Japanese AGC glass with 18 layers of optical coating, offering 1–5 stops of light reduction—ideal for moderate lighting conditions, from partly cloudy to sunny days. The universal 58mm threaded ring allows compatibility with other filters and stacking for creative effects.

For safety and convenience, the holder features non-slip silicone pads, a shock-absorbent bezel, a lanyard hole, and an included lanyard to prevent drops. A multifunctional matte EVA storage bag with mesh pockets and elastic bands keeps the magnetic mount and filters organized and protected, while compact dimensions (16×11×4.5cm) make it easy to carry along with other accessories. Optimal performance is achieved when used on a bare iPhone; limited use with Apple official cases is supported using the included magnetic ring.
