No, the ND filter from the magnetic set is an ND1000 (increases the shutter speed by a factor of 1000). However, it would also be technically difficult to implement a magnetic, yet adjustable, ND filter.

Hello, there is a magnetic adapter ring included. If the MCUV filter is not required, the magnetic adapter ring can be used to attract the CPL or ND1000 filter directly.

1. The UV filter can be used alone. ND and CPL need a matching magnetic adapter ring, because the camera lens itself is not magnetic and cannot be directly attracted to ND and CPL
