The Urth 72mm Magnetic Infra-Red (R72) Filter Plus+ is a specialized photo filter for infrared photography. This 72 mm diameter filter features a magnetic attachment system for quick and secure mounting on compatible lenses, allowing photographers to efficiently switch between different filter types. The designation R72 indicates that it blocks visible light below approximately 720 nanometers and allows infrared radiation to pass through, enabling creative infrared effects in both digital and analog photography. Made from high-quality optical glass, the filter maintains image quality with minimal distortion or color shift. The magnetic mounting mechanism provides a reliable connection without threading issues, and the slim profile helps to avoid vignetting with wide-angle lenses. This filter is compatible with various camera systems when appropriate adapter rings are used, making it suitable for landscape, architecture, and experimental photography where infrared effects are desired. The Urth 72mm Magnetic Infra-Red Filter is a practical tool for photographers looking to explore infrared techniques without permanent camera modifications.
