The PolarPro Macro Lens is a specialized accessory designed to enhance the close-up capabilities of GoPro cameras, particularly the HERO3, HERO3+, and HERO4 models. This lens reduces the camera's minimum focusing distance, allowing for sharp focus on subjects positioned between 3 to 18 inches from the lens. Such functionality is ideal for capturing detailed shots of small subjects, making it a valuable tool for creative close-up photography and videography.
