With the Black Eye HD Macro for smartphones you can increase a subject up to 15x. This set consists of a clip and a macro lens. Attach the clip as a clothespin to the camera of your mobile phone. Here you turn the macro lens. With this lens you have a focusing distance between 20 and 26 millimeters. This allows you to take sharp photos of subjects that are very close. The coating on the lens prevents reflections and image distortions.
