The PolarPro Macro Lens for the GoPro Hero4/3+ is an excellent tool for capturing detailed close-up shots you just can't achieve with the camera alone. This macro lens reduces the camera's focal length allowing the GoPro to focus at distances between 3 and 12 inches away from the subject. Without a macro lens the GoPro will not focus on a subject closer than 12-inches away. The PolarPro Macro Lens is a great creative tool for capturing creative close-ups for both your photos and videos. This macro features a simple press on/off installation and an HD glass lens for beautiful and crisp optics; as well as maximum scratch resistance. The macro is a great lens to have in your gear bag as it expands the capabilities of the GoPro Hero4/3+'s focal range dramatically.
