Fotodiox Ninja 55mm Magnetic Filter Adapter Kit

SKU CH-C4FT-VGCZM

A magnetic 55 mm filter adapter with a 32 mm octagonal opening that attaches to any smartphone or tablet for mobile photography

  • Magnetic attachment works on any smartphone or tablet
  • 55mm thread accepts standard photographic filters
  • 32mm octagonal opening prevents vignetting on wide lenses
  • Anodized aluminium construction protects device surfaces
  • Rotatable core enables horizontal and vertical compositions

Universal Mobile Filter Adapter

The Fotodiox Ninja 55mm Magnetic Filter Adapter Kit enables smartphone and tablet photographers to attach 55mm threaded filters using a magnetic core system. It ships with adhesive metal plates that secure the core to any device surface regardless of camera placement. The anodized aluminium construction protects the device finish while providing a stable platform for creative filter work.

Best for Flexible Phone Photography

This kit suits creators who want to use circular polarisers, ND filters or other 55mm glass on iOS or Android phones without a dedicated case mount. The rotating magnetic core supports both horizontal and vertical compositions. Photographers requiring a fixed thread on a specific case or those using filter sizes other than 55mm will need a different solution.

55mm Thread with 32mm Clear Aperture

The adapter accepts standard 55mm filters and offers a 32mm octagonal opening that covers most phone lenses without vignetting. The magnetic hold is strong enough for typical shooting but can release under heavy impact. Users stacking multiple thick filters may reach the limit of the magnetic grip and should verify clearance for their specific lens position.

Questions about this item

Will the 55mm thread fit my existing circular filters?

Yes, the adapter has a standard 55mm thread that accepts any 55mm screw-in filter.

Can I still use a phone case with the magnetic core attached?

The kit includes two metal plates that slide between the phone and case so the magnetic core holds through most slim cases.

How do I know the 32mm octagonal opening is aligned with my camera lens?

The magnetic core rotates freely; turn it until the opening sits directly over the lens and the filter sits flush.
