The JJC S+ L39 Ultra SlimMC UV Filter with a diameter of 77 mm is a high-quality screw filter specifically designed for use with various lenses. This UV filter primarily serves to block unwanted UV rays that can affect image quality. Additionally, it protects the front lens of the camera from scratches, dust, and other environmental influences, thereby increasing the longevity of the equipment. The ultra-slim design of the filter minimises the risk of vignetting, especially in wide-angle shots. The multi-coating technology ensures high light transmission and reduces reflections, resulting in clear and sharp images. The JJC S+ L39 Ultra SlimMC UV Filter is therefore a sensible addition for photographers who value image quality and the protection of their equipment.
