Urth Infrared (R72) Lens Filter Plus+ - 67mm

R72 indicates that the filter transmits infrared light starting at 720 nanometers (nm) and blocks visible light below that wavelength.

No, this filter is only effective on cameras that are sensitive to infrared light and do not have a strong internal IR-blocking filter. Most standard consumer cameras have IR-blocking filters.

Expect unique transformations like white foliage, dark skies, and surreal textures. It's particularly effective for landscape photography, turning familiar scenes into dreamlike images.

You need an IR-sensitive camera. The lens itself doesn't need to be specialized, but you should use a filter size that matches your lens thread. Wider lenses might exhibit more vignetting.

Infrared light can sometimes interfere with autofocus systems, especially in low light. You may need to manually focus or use your camera's focus assist features after recomposing.

Use a soft lens brush for dust and a microfiber lens cloth for smudges. For tougher marks, a lens cleaning solution can be used sparingly on the cloth.

Urth backs this filter with a lifetime warranty.

Confirm your camera has an IR-sensitive sensor and no strong internal IR-blocking filter. Check if the filter is screwed on correctly. You may need to adjust exposure settings (longer shutter speed or higher ISO) as infrared light levels can vary.

While the ultra-slim rim minimizes this, heavy vignetting can occur on wider-angle lenses. Try stopping down the aperture (using a smaller f-stop number) or cropping the image in post-processing. Consider using a wider lens if possible.

Ensure you have the correct filter size for your lens. Clean the threads on both the lens and the filter. Avoid cross-threading; screw it on straight and gently. Do not overtighten.
