This 77mm X-Series IR720 Infrared Filter from Zuma passes infrared light while completely blocking other wavelengths of light in the visible spectrum. Unlike the eye, silicon- based CCD and CMOS image sensors have sensitivities extending into the near-infrared, which may extend to 1000nm. Digital cameras are typically equipped with an IR-blocking filter to prevent unnatural-looking images. IR-passing filters, or removal of factory IR-blocking filters from the camera, are commonly used in infrared photography to pass infrared light and block visible and ultraviolet light.

This IR filter easily screws onto a standard 77mm filter thread, blocking UV and visible light in the spectrum up to 720nm. While appearing black to the human eye, it transmits infrared light through to the IR sensitive image sensor. When taking pictures interesting effects can be achieved, since infrared is actually heat, so living subjects that transmit or reflect heat will appear to be bright. Infrared photography opens up a whole new way of looking at the world aside from conventional visible light.

Related Questions and Answers

Q: 1. What is the thickness of the filter?

A: The Kolari 100 x 100mm Infrared Pro Filter (720nm) would be 2mm thick.

Q: 2. Will this vignette on a Nikkor z 40mm f2 with a UV lens protector?

A: No, there is no vignetting when attaching the Zuma 52mm Standard Screw-In Metal Lens Hood to the Nikon NIKKOR Z 40mm f/2 Lens on a full-frame camera body. You can mount the lens hood on top of the lens filter.

Q: 3. Is it compatible with the A7R V?

A: No, the Kase IR 590 Infrared Filter for Sony Alpha Cameras does not fit the Sony a7r V.

Q: 4. Is this nano coated?

A: B+W 72mm MRC Basic Circular Polarizing Filter BH #BWCPB72 comes with Multi-Coating and Resistance-Coating.

Q: 5. I own a Nikon D5500, which I understand does not have an optical low-pass filter. The product description for this filter indicates the camera requires a "conversion" to eliminate the low-pass filter. My question: will this filter work as intended without the "conversion" for the D5500? Thanks. Frank

A: No, to use the Kolari Vision Infrared Lens Filter (52mm, 590nm) the camera sensor in the D5500 needs to be modified. It will not work correctly with that.

Q: 6. How much light do I lose using this filter? Will I be able to hand hold the camera at ISO 200 and f2.8?

A: Using the Kolari Vision Pro Gen 3 Infrared Lens Filter (780nm, 77mm) on a camera not converted to IR the filter will block 10-15 stops. Using it with an IR converted camera it will be about 1-2 stops of light.

Q: 7. Will this filter work well on a Nikon D850?

A: My base settings on the D810 was, 30 sec, f/8, ISO 400. Early morning with shade. I was pleased with the results.

Q: 8. can this be used on a zeiss .cp3 ? will it cause vignette if so ?

A: We're afraid not. Zeiss CP3 lenses are cinema lenses that do not have a filter thread, they have a 95mm front diameter, not a threading for a filter like this. This filter is not compatible with a CP3 lens.

Q: 9. Can this IR filter be used with Rollei Infrared 400 Black and White Negative Film? Is an approximate filter factor available?

A: The Kolari Vision 100 x 100mm Infrared Pro Filter (720nm) can be used with Rollei Infrared 400 Black and White Negative Film. This should have a filter factor of 1 when used with IR film or a sensor modified for IR. The 720nm filter works out to having about as much IR light available as a normal camera has visible light, the easiest to expose for.

Q: 10. Difference between this polarizer and the high transmission version?

A: B+W High-Transmission MRC-Nano Master Circular Polarizer Filter has the nano coating that beads water and makes it easier to clean and also protects the filter against scratches. The basic filter does not have that. The high transmission filter also allows more light to reach the camera than the basic version. The high transmission polarizer filter is also equipped with a grease-free rotating device for smoother rotation.
