The Urth 39 mm Infrared R72 Lens Filter Plus+ is designed for photographers looking to explore infrared photography. It blocks all visible light wavelengths below 720 nm, allowing for the capture of normally invisible infrared light for surreal, high-contrast images. Made from high-quality German SCHOTT glass, it ensures professional clarity and true color balance. A 20-layer nanocoating provides robust protection against water, oil, and scratches, as well as improved light transmission for sharper results and easier cleaning. The filter features an ultra-thin edge made of durable magnalium to prevent vignetting and double-threaded connections for stacking with other filters or for the use of screw caps, enhancing the versatility of your photography equipment. With a diameter of 39 mm, it is ideal for outdoor and nature photography, transforming ordinary scenes into otherworldly visuals with added depth and fine colors. Please note that this filter is not compatible with cameras that have an internal IR cut filter, so be sure to check your camera specifications before use. Designed for reliability and long-term durability, it supports creative experimentation without compromising on quality and is a dependable choice for expanding photographic possibilities.
