The HOYA R72 Infrared filter is designed for infrared photography with digital cameras and infrared film. This nearly opaque filter blocks all visible light up to 720nm and passes lights from the very high red edge of the visible spectrum and infrared light. This allows you to capture the lights that are not visible with naked eyes and normal conditions. Due to the nature of infrared light, filter factor and exposure compensation vary widely from visible light and depends largely on lighting conditions.

• Works well with digital cameras, especially mirrorless cameras or DSLRS with no IR blocking filter in front of the sensor. (Please check your camera's manual).
• The filter completely transmits the light at 760nm - 860nm. (infrared spectrum) with the light transmission 95%.
• Can be paired with coloured black and white contrast filters such as the R25 (red), K2 (yellow), O (orange) or other colour filters to change the colour rendition or contrast effects.
