NEEWER Magnetic Filter Kit

Yes, these filters are designed to work with M-mount phone cages or cases. They will not attach directly to a bare smartphone, so ensure your current setup supports the M-mount system before purchasing.

The magnetic connection is strong enough for standard handheld shooting and walking. However, if you are planning on high-intensity activity or mounting the phone to a moving vehicle, you may want to secure the filter with an additional tether or tape.

The kit is designed for quick-swapping individual filters rather than stacking them. While the magnetic system is convenient, stacking multiple filters can introduce vignetting or image quality degradation, so it is best to use them one at a time.

The 30-layer nano-coating is primarily there to reduce lens flare and ghosting while repelling water, oil, and dust. This ensures your footage remains sharp and clear, even when shooting in bright, challenging lighting conditions.

Yes, as long as your phone cage uses the standard M-mount interface, these filters should fit. They are compatible with cages from brands like SmallRig that utilize the same mounting specification.
