Designed to bring more of the scene into each image, the black 18mm Wide-Angle Lens from Sirui converts the 29mm lens on most phones into an 18mm wide-angle lens with a 95° field of view, which allows users to capture more of their environment in their photos. This is especially useful for landscapes, architecture, and interior photography, as well as confined spaces and environments where the photographer may not be able to move further away from a subject when shooting it.
