The SmallRig 5832 magnetic filter set is compatible with the DJI Osmo Pocket 3 camera and includes three filters: variable ND2-32, CPL, and Black Mist 1/4. The ND2-32 filter adjusts exposure, the CPL reduces reflections from non-metallic surfaces such as water and glass, and the Black Mist 1/4 softens bright areas. Magnetic mounting makes it easy to swap filters, while the slim design allows the gimbal to move without interference. The diameter is 37 mm. It is not compatible with lens protectors or the original OEM wide-angle lens.
