Kase DIY Magnetic Screw-In Adapter Ring Kit (58mm)

The Kase 58mm DIY Magnetic Screw-In Adapter Ring Kit allows you to convert conventional 58mm screw-in filters to the magnetic type. The kit includes two rings. One ring is magnetic on one side and has 58mm male threading on the other. This ring screws onto your camera lens. The second ring is magnetic on one side and has a 58mm female thread on the other. Screw your filter onto this second ring. Then magnetically mount this second ring onto the first one that's already on the camera lens. Filters heavier than 2 oz, such as certain variable ND filters with brass rings, are not recommended.
