The Heliopan 24mm RG610 Infrared Filteris designed to help capture images of how a subject reflects or transmits infrared light.

Infrared light waves occupy the space in the electromagnetic spectrum behind visible light due to their longer wavelengths. Many surfaces and materials react to, or emit infrared light waves differently than visible light waves, which provide the potential for photographs of subjects or subject properties that are otherwise invisible to the human eye. Such images require an infrared-sensitive medium such as infrared film or a digital photographic sensor which may be more effective when used without the infrared-blocking filters that are frequently built over them.

Conventional light sources such as the sun, photographic strobes, or incandescent lighting may be used to provide infrared illumination. However, because infrared films or digital photographic sensors can be more sensitive to the relatively higher energy and shorter-wavelength visible light those sources also emit, the effects of infrared light can be otherwise obscured. The Heliopan 24mm RG 610 Infrared Filter makes it possible to capture images of how subjects are illuminated by infrared light by blocking near-infrared, visible, and ultraviolet light waves while allowing 90% of infrared light waves 610nm or greater into the lens it is mounted onto.

This filter is constructed from Schott glass for increased optical clarity and features a thin brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention.

• Designed for use with infrared film or digital camera sensors by filtering out near-infrared, visible, and ultraviolet light
• Allows 90% of infrared light waves beginning at 610nm to pass through
• Effective for infrared films or other media sensitive to infrared wavelengths 610nm or above
• Constructed from Schott glass for optical clarity
• Each glass surface includes four layers of anti-reflection coating to prevent internal ghosting and reflections
• Filter factor of approximately 8x reduces exposure by about 3 stops
• Thin, brass filter ring helps to prevent vignetting, jamming, and provides additional strength
• 24mm front filter threads allow for use with other filters
• Plastic case for storage and transport

Q: 1. Hello! is the holder ring provided with this filter? I need to fit this filter on a 52mm thread lens

A: The Heliopan Series 8 Infrared RG 850 Filter listed above is designed for usage on lenses that have a Series 8 bayonet filter mount. We have no lens mount adapters that would be compatible to connect this filter onto a lens that uses 52mm filter threads. If you own a lens with 52mm filter threads, I would instead recommend the Heliopan 52mm RG 850 Infrared Filter, B&H # HEIR85052, for your usage needs.

Q: 2. I recently purchased a Nikon D7100. What kind of results, if any, can I expect if I put one of these filters on it?

A: You may not get the expected results! Most cameras would not give you the effect unless you convert the camera, which will be permanent and expensive too! There are some old models which do not have built in ir cancellation mechanisms. Those are the ones which can generate ir effects.

Q: 3. What is the range of filter diameters available goth the Series 7 & 8 filters?

A: I'm not sure I understand the question, can you rephrase?

Q: 4. What additional features are found in the Series 8 filters when compared to those of Series 7?

A: Series 7 or Series 8 simply refers to size only.

Q: 5. What size in millimetres is Series 7 or 8?

A: The diameter of this Heliopan Series 8 Infrared RG 715 (88A) Filter is 63.5mm, but this filter does lack threading.

Q: 6. 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: 7. will this work on sony alpha cameras? i heard you need to modify the camera in order for this to work? I have a7s and a6500

A: The filter works perfectly without any changes to the camera, do you need to do some post processing and you can check on YouTube. I highly recommend the filter

Q: 8. Will this work with a Canon R5?

A: The Hoya 67mm R72 Infrared Filter will fit any lens that has a 67mm filter thread. You can use the filter on a lens that is attached to the Canon R5.

Q: 9. Will this fit on a rolleiflex 2.8d?

A: Yes, a Bay 3 or bay III filter will fit on the lenses of a Rolleiflex 2.8 D.

Q: 10. will it work with a Pentax 645D?

A: mmmmI' don't think soThat camera is too new.The IR filters works better with older digital cameras like the Nikon D50, D70 and D80, D100 (2001 - 2006)
