The iPhone X Dual Lens Kit from Sirui bundles their red iPhone X Mobile Phone Protective Case with a dual lens system, which is made up of a wide-angle lens and a medium/long focal length lens. This dual lens system is attached to the protective case and can help you capture higher quality images with unique perspectives that are different from your phone's built-in camera. The dual lens can also be removed and replaced with one of Sirui's single lenses, such as their wide-angle, portrait, fisheye, or macro.
