K&F Concept CPL filter for iPhone 17 Pro / Pro Max, snap-on, dark blue

CPL filter for iPhone 17 Pro / Pro Max, snap-on, dark blue. It snaps onto the camera module with one press, cuts reflections from water and glass and deepens the colour of skies and foliage.

Made for the iPhone 17 Pro and 17 Pro Max. Also fits the iPhone 16 Pro, 15 Pro and 14 Pro, where it may however obstruct the flash and LiDAR.

Snap-on with one press, MagSafe stays clear

The filter is moulded precisely to the camera module of the iPhone 17 Pro and 17 Pro Max: press it on and it settles into position by itself, with no thread and no adapter. The rubber ring inside stops it slipping and protects the camera glass. The MagSafe magnetic ring stays clear, so charging, mounts and power banks keep working — and the filter works with most cases that have an open window around the camera.

Reflections in glass

A polarising filter removes reflections from non-metallic surfaces. In a shop window or behind the glass of a café the mirroring disappears and you can see what is behind the pane.

Water and sky

On water and in the sky the effect is most obvious: the surface stops mirroring, the bottom shows through, the sky darkens and the clouds stand out. You set the strength by turning the frame — the motion is damped and stepless.

AGC glass with a 28-layer coating

The glass is AGC optical glass with a 28-layer coating and 99.5 % transmission. It repels water, resists scratches and keeps reflectance low, so it adds neither haze nor ghosting to the image.

Aluminium frame, about 9.5 g

The frame is CNC-machined from aluminium and weighs about 9.5 g. With the filter on, the phone still balances easily on gimbals such as the DJI OM. The colour is matched to the iPhone 17 Pro finishes.
