Details


Optical glass and layered coatings help reduce reflections while repelling water and oil.


Choose UV for lens coverage or ND8, ND16, and ND32 filters for bright-light exposure control.

ND strengths progressively reduce incoming light, while the UV option can help limit unwanted light interference.


The lower tab seats in the lens groove, then the upper latch presses into place until it clicks.



At 0.8 g per filter, the compact frame adds minimal weight to the camera module.


Single-filter packs include one selected filter and a cleaning cloth; the set includes all four filter types.
