FishEye Inon UFL-G140 SD

Ultra Wide Also Underwater. Although an action camera is equipped with ultra-wide lenses, its underwater coverage will shrink significantly due to the different ratio of refraction between air and water. For example, the maximum angle of view of GoPro® HERO6 Black is approx. 151 ° on earth that will shrink up to approx. 94 ° when we put the camera in a real housing for diving and we bring it underwater because of the different index of refraction. INON UFL-G140 SD provides ultra-wide semi-wide-angle images with 140 ° viewing angle underwater allowing you to perform wild underwater videos only with action cameras. * Angle of field measured by INON or calculated angle of field underwater based on the measured field angle. Not confirmed by camera production. The measured visual angle of "HERO3 + Silver Edition" is approx. 142 ° (air) which is less extensive than the "Black Edition". So the viewing angle underwater with this lens is less than 140 °. The "HERO3 + White Edition" has not been tested.
