The Urth 39 mm Magnet Infrared (R72) Filter Plus+ is a specialized photo filter for infrared photography. With a 39 mm thread diameter, it is compatible with various camera lenses and utilizes a magnetic attachment system for quick mounting and removal. The R72 designation means it blocks visible light below approximately 720 nanometers while allowing infrared radiation to pass through, enabling creative infrared photography effects. Made from high-quality optical glass, this filter maintains image quality with consistent infrared transmission properties. The magnetic attachment mechanism allows for fast filter changes without threaded screws, making it practical for photographers in changing conditions. The filter is designed to minimize light leaks and ensure a secure fit during use. At 39 mm in size, it is suitable for compact camera systems, certain prime lenses, and specialized photography equipment. The infrared transmission properties allow for unique monochrome shots with characteristic foliage representation and atmospheric effects. This filter is designed for photographers looking to explore creative infrared techniques, architectural photography with enhanced sky contrast, and artistic landscape applications. The magnetic system offers operational convenience while maintaining consistent optical alignment. The filter construction includes multi-layer coatings to reduce reflections and enhance optical clarity. Careful handling is recommended to preserve the optical surfaces and magnetic components. This product represents a specialized tool for photographic experimentation and creative image design with infrared-sensitive camera systems.
