[ AOI ] UWL-03 Wide Angle Conversion Lens 0.73X Wide-angle lens for GoPro This is an underwater wide-angle lens. It is being sold because I have had fewer opportunities to use it. *Photo 2: There are minor scratches on the lens mark and other areas. I didn't feel they affected the images much and didn't mind them, but please refrain from purchasing if you are concerned. Please refrain from purchasing if you are overly concerned, as this is a subjective assessment.
