How to: 101

1/4

Determine Filter Size

Match the diameter (e.g. Ø49mm) on your lens to the filter size. This is different to focal length.

2/4

Mount the Magnetic Adapter Ring

Thread the Magnetic Adapter Ring to your lens. Avoid overtightening.

3/4

Attach the Filter

Align the white locking mark on the filter with the smooth section of the adapter ring, and rotate counterclockwise until the white locking mark reaches the lock position.
