The only downside is that blenda shadowmaker for the camera for the drone camera can not be installed on top of these filters

Great filter set compatiable with phantom 4 metal filter rings coated glass lens uv and cpl is double side coated which improves light transmissionvariable nd is not coated at allnd 16 is coated in the front of the lens onlyweight of uv and nd16 is undetectable on my kitchen scale while variablend and cpl which have a rotatable ring design is weighted at 20 gram7ozeven with the weight of two heavier filters when gimbal is powered on and calibrated they do not drag the lens head downwards the head is pointed straightlevel with horizonupdatetried the variable nd filterthe image quality suffered significantly 4k footage looks like it was shot in 720p
