The SmallRig 52mm Universal Magnetic Filter Adapter Ring allows you to attach a 52mm lens filter to your smartphone and makes it possible to take better cinematic photos and videos.

With a circular polarizer your colour saturation is improved, by reducing reflections, for improved exposure in bright environments a neutral density filter is used, or to protect the lens element a UV filter can be attached. Separately available magnetic filters can be attached to the adapter ring, while the adapter itself secured to the phone with a clamping knob. You will also find rubber anti scratch cushions on both sides to protect the phone.
