PolarPro DJI Osmo Pocket 3/4 Shutter (ND8/ND32/ND128)

The filters are of good optical quality and help when filming at longer shutter speeds, such as 1/50. They are very small, and the magnet that holds them in place is very strong, making it difficult to remove the filter from the camera. The major drawback, however, is that they are too thick: 3mm. This prevents the camera from returning to its original position when you turn it off. This leaves the lens and filter exposed when you store it. Occasionally, the camera does return, but then you can't turn it back on because it gets stuck. The only way to prevent this is to attach the filter after turning the camera on and remove it before turning it off. But this is such a hassle, because you have to turn the camera off after every shot otherwise the battery will drain. I'm going to return the filters. Hopefully, DJI's own filters are a bit thinner.
