K&F Concept Clip On 67mm Variable ND2-32 Magnetic Phone Filter Kit

In this review of the K&F Concept Clip On 67mm Variable ND2-32 Magnetic Phone Filter Kit, the bottom line is simple: this kit is for smartphone photographers who want SLR-like control over exposure without swapping to a larger camera. The standout reason to buy is the magnetic VND filter that provides 1-5 stops of light reduction while preserving natural color, letting users slow shutter speeds or open apertures for motion blur and shallower depth of field. The clip and magnetic adapter make changing filters quick, which matters for run-and-gun shooting on phones.

Key Features

• Magnetic quick swap: The magnetic design lets you attach and replace filters rapidly so you do not miss fleeting moments.
• Variable ND control: The ND2-32 filter offers 1-5 stops of light reduction, enabling longer exposures and wider aperture looks on mobile cameras.
• Optical quality: Made from AGC optical glass with 18 multi-layer coatings to reduce reflections and maintain natural color and contrast.
• Secure phone clip: The clip includes dual side rubber pads and a groove snap on the adapter ring to prevent rotation and protect the phone finish.
• Accessory-ready mount: A cold shoe on the clip accepts an LED fill light or wireless mic to improve low-light video capture.
• Wide compatibility: The 67mm magnetic base fits other K&F magnetic filters and can be used on cameras with a 67mm thread via an adapter ring.

Who It's For

This kit is best for mobile photographers and content creators who regularly shoot landscapes, long-exposure scenes, or video on a smartphone and want precise control over exposure without carrying a separate camera. The magnetic system and cold shoe make it useful for vloggers who add a light or mic and need a stable clip mount.

It is less suited to users who never need variable ND control or who prefer built-in phone accessories; also, photographers seeking heavier-duty weather sealing or full-frame sensor performance should look at dedicated camera filters instead.

Frequently Asked Questions

Will this clip fit my phone?

Does the ND filter change color?
No, the AGC optical glass and 18 multi-layer coatings are intended to maintain natural color and reduce reflections, so color shift is minimal in normal use.

Can I use other filters with the clip?
Yes, the 67mm magnetic base accepts other K&F Concept 67mm magnetic filters including CPL, UV, and effect filters, and can interface with camera lenses via a 67mm magnetic adapter ring.
