Before buying the Freewell Insta360 Luna Ultra Glow Mist Filter, confirm that your camera or drone model is Luna Ultra Glow Mist. 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 soft highlight glow and a more cinematic look. 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.
