- #2 in Camera Lens Infrared Filters
The HOYA R72 Infrared filter is specifically designed for infrared photography with digital cameras and infrared film. Infrared light starts in the high-red area of the visible spectrum at around 750nm and goes up beyond 1000nm. This light is not visible to the naked eye. Looking through the R72 filter it looks almost opaque because the filter is only passing light from the very high red edge of the visible spectrum and infrared light. Infrared photography yields very interesting, sometimes stunning, and creative result as object in a scene reflect infrared light differently than normal light. 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 owners manual). The filter completely transmits the light at 760nm - 860nm. (infrared spectrum) with the light transmission 95%. The HOYA R72 is constructed using high-quality optical glass from Hoya mounted in a precision milled aluminum frame that provides rigidity. Consistent quality, made in Japan. Can be paired with colored black and white contrast filters such as the R25 (red), K2 (yellow), O (orange) or other color filters to change the color rendition or contrast effects.

Great quality filter, returned cause I didn’t get the desirable results I was hoping for. I have sony cameras and apparently the newer the sensor technology the more infrared light it blocks. The filter didn’t do much. Long exposures and tripods are a must if you go the filter route. Didn’t get much color separation and everything foliage looks fuzzy cause the long exposures. Overall mediocre results, next thing for me, convert one of my cameras to IR.If you own a fuji camera you’ll get better results or maybe other brands your mileage may vary.

Compré este filtro porque es el que recomiendan en algunos cursos de esta técnica. La calidad está muy bien, ya lo he incorporado a mi colección de filtros y aunque viene con una caja yo lo guardo con otros en un estuche. Al utilizar filtros la técnica infrarroja te obliga a largos tiempos de exposición pero para iniciarte este filtro esta genial y sale muy bien de precio. Para regalarlo con algún libro de la técnica a algún aficionado de la fotografía, se abren un nuevo mundo de posibilidades, recomiendo probarlo.

This filter became a kind of standard tool in IR photography. I use it with a full spectrum camera and I am quite pleased with it.

Hoyas are expensive but results are great. Images are crisp and sharp unlike cheaper IR filter I tried before

This filter blocks nearly all visible light. Consequently, it looks opaque and black to the naked eye, though if you hold it up to a strong light source, you will be able to see a dull, deep red image through it. The R72 is one of the most common filters used in infrared (IR) photography. If you get really serious about shooting in IR, you may want to look into having your camera modified to remove its built-in IR-blocking filter, but even with that filter in place, some cameras can be used for IR photography, given a suitably long exposure. (Incidentally, what we are talking about here is "near-infrared" light, which, although invisible to our eyes, behaves very much like normal light in the way it reflects off objects. This is not the same as seeing heat as light, which involves a deeper portion of the IR spectrum.)I have used this filter with an unmodified Canon EOS 5D Mark II digital SLR camera and a Canon EF 50mm f/1.8 lens (the original version from the 1980s, not the all-plastic one made now, which may or may not take the same size filters). The camera's auto-focus capability works perfectly with the filter in place. In direct sunlight, I have found that with the camera on a tripod, an exposure of about 15 seconds at f/5.6, ISO 400 produces a good image. After that, what to do is a matter of creative judgment; the picture obviously won't be in natural colors (that's the whole point of shooting in IR), so you can adjust white balance however you like. I often exchange the red and blue channels, as well. Sometimes I reduce the end result to grayscale, sometimes not.Now, one may ask at this point, if we are photographing infrared light, what is all this talk of red and blue and white? The answer is that the camera's sensor, though designed primarily to pick up visible light, is also somewhat sensitive to IR. However, the camera cannot distinguish between IR and visible light. The IR that it senses, it records (incorrectly) as shades of visible light (mostly red). This is what we see in digital IR photography. We are seeing, in colors we can see, an image made from light that we cannot see directly.IR photography is a lot of fun and at times it provides a strange sense of discovery. It is strange and sometimes thrilling to see our familiar world in such an unfamiliar way. The Hoya R72 filter is a good choice for IR work.

After reading reviews all across the web, the concensus was that this is the best all-purpose Infrared filter for photography - digital photography in my case. It is also a reasonably priced. I ordered mine and got it quickly, and tried it out right away. The user photos above are ones I took when I did some of my first tests.On a tripod and with the proper settings, this filter does what it is supposed to and does it well. It darkens the sky and lightens the foliage (Woods effect). It gives images an otherworldy appearance that many find appealing.I know that I will be using it quite a bit for my nature photography. Thank you Hoya!EDIT 08/07/2014: I just wanted to clarify that you do not need an infrared modified camera to capture IR photos using this filter. It will work on a standard digicam, though results will vary from camera to camera. Some may exhibit a "hot spot" (brigther central area) and exposure times are long si will require the use of a tripod. If it is windy, some foliage may blur, but that also can be interesting. If you want to capture infrared images of people and other subjects using a more standard exposure time, you will need an IR modified camera.
