49mm Infrared R72 Filter for Creative Photography
This 49mm circular filter blocks all visible wavelengths below 720nm, letting only infrared light reach the sensor. It is built with German SCHOTT glass and a 20-layer nano-coating for high transmission and easy cleaning. The ultra-slim rim reduces vignetting on wide-angle lenses. Outdoor and nature photographers use it to reveal surreal tones in foliage and skies.
Suited for Infrared Experimentation.
The filter cuts the entire 400 to 700nm visible spectrum, so normal colour photography is impossible while it is fitted. Buyers who want a filter for everyday protection or colour enhancement should choose a different type. Videographers needing autofocus reliability in standard light will also find this unsuitable. It is made specifically for creative infrared work.
Simple Thread Mount with Double-Threaded Design
Screw the filter onto any 49mm front thread; the ultra-slim rim helps avoid corner shading on most lenses. Double threading allows a lens cap or another filter to be stacked on top. The main issue is the extreme light loss — exposure times become very long, so a tripod is essential. Autofocus may struggle because the camera meters visible light, not the infrared band.

Questions about this item
Does this 49mm filter thread onto a lens that already has a 49mm front thread?
Yes, the filter has a 49mm thread that matches a 49mm lens front, and its double-threaded rim lets you stack another 49mm filter or cap on top.
Will the R72 filter work normally on a standard DSLR or mirrorless body that still has its internal IR-cut filter in place?
The filter passes only light above 720nm, so a stock camera with its internal IR-cut filter will need much longer exposures or a tripod to record infrared images.
How can I confirm the 20-layer nano-coating is performing after I mount the filter?
Check for clean, flare-free infrared shots with strong contrast between foliage and sky, and verify that water or oil beads off the glass surface.
