Before buying the Freewell DJI Osmo Action 5 Pro ND/PL Filters 4Pack, confirm that your camera or drone model is Osmo Action 5 Pro. Freewell filters are made for specific camera housings, so a similar-looking DJI or Insta360 model may still need a different filter size or mount.
Next, check the job you want the filter to do. This product is best for reducing glare from water, glass, roads, snow, and bright skies. If your goal is only basic lens protection, choose UV protection. If you need shutter-speed control in bright sun, choose an ND or VND option. If reflections are the problem, look for PL, CPL, or ND/PL in the product name.
