The Sony VFA-305R1 Filter Accessory Kit serves multiple purposes when teamed up with your Sony RX0 ultra-compact camera. This kit includes a 35.5mm filter adapter, multicoated UV filter, and lens hood. The UV filter keeps the camera lens pristine, without any scratches, and prevents UV rays from damaging its elements. The lens hood blocks stray light from entering the lens and helps maintain the contrast in the recorded videos. The filter adapter comes in handy when you wish to insert 35.5mm filters on the camera lens for a variety in effects in your videos.
