SUMMARY
The Urth Infrared Filter Plus+, also known as the 'I-Red 72', is an eco-friendly 720nm filter designed for monochrome infrared photography. It features a premium build with aerospace-grade aluminum, German Schott B270 glass, and a 20-layer nano-coating for clarity and contrast. The filter is available in screw-in or magnetic round formats with thread sizes from 37-95mm. While it performs well on IR-converted cameras, it lets too much visible light through for standard cameras. The included metal hard case was noted as a disappointment due to fibrous foam, but the filter itself is praised for its performance and hydrophobic coatings.
