K&F Concept 58mm Magnetic Filter Adapter for iPhone 17 Pro Max with Variable ND2-32 Filter

The K&F Concept aluminium adapter fits on the back of the iPhone 17 Pro Max and takes standard 58mm screw-in camera filters. It holds magnetically, its cutouts line up with the cameras, flash and antenna, and the outer side is magnetic too, so a light, grip or tripod can snap onto it. The kit includes a variable ND2-32 filter that cuts 1 to 5 stops of light – for slower shutter speeds, motion blur or a wide aperture on a bright day.

On in a second

A set of 17 N52 magnets holds the adapter to the phone with up to 2,500 gs (about 8 N). Another 8 magnets on the outer side make it a double-sided magnetic mount – attach a magnetic grip, fill light or tripod to it.

Silicone and a lanyard against drops

Large non-slip silicone pads cover both sides, the edges absorb knocks and a wrist lanyard runs through the lanyard hole. The aviation-grade aluminium body is rigid, light and dissipates heat well.
