Before buying the Freewell DJI Mavic 4 Pro UV Filter, confirm that your camera or drone model is Mavic 4 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 daily lens protection while keeping the camera view clear. 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.
