The Heliopan 58mm RG 1000 Infrared Filter is 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 58mm RG 1000 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 70% of infrared light waves 1000nm or greater into the lens it is mounted onto.

Because of the degree to which the Heliopan 58mm RG 1000 Infrared Filter blocks the electromagnetic spectrum up to infrared light waves 1000nm or greater, proper exposure is determined by the infrared sensitivity level of the film or imaging sensor behind it. The particular intensity of infrared-emitting light sources, as well as the relative location of the camera and lens on which this filter is used, can also influence exposure.

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.

Q: 1. hI, will this work on nikon p900? if so, will I have to modify the camera..thanks

A: This lens is designed for SLR and DSLR cameras.

Q: 2. 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: 3. 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)

Q: 4. How long (deep) is the LONG lens hood?

A: It is about 1 and 5.8th inches long.

Q: 5. Will this lens hood cause vignetting with 24mm full frame lens?

A: This hood is suitable for 50mm or higher. It may cause vignetting on wide angle lenses like a 24mm lens.

Q: 6. I was planning on shooting both in color and B&W in raw format and was wondering what type of a result i will get in color mode?

A: A RAW color image shot with an infrared filter will produce a yellow/red image with blue foliage.

Q: 7. Will this fit a PVS-14 objective lens?

A: This will not work with that Model.

Q: 8. What is the height/length of this lens hood (less male screw threads)?

A: Length is less than 10mm for Heliopan 39mm short lens hood.

Q: 9. Will it leave some soft color? Or will it always look B&W? Or, was the sample image converted to B&W?Thanks,MJ

A: That filter only lets the infrared spectrum of light to come through and hit the sensor. And IR light is Red. So you can convert it to black and white or change the white color balance to achieve different IR color effects. You can do all this in post with programs like Photoshop or Lightroom.

Q: 10. How many stops of light do you loose with this filter?

A: I don't have the exact figures with me here, but on a bright full-sun day my exposures using a Canon 5D MKIV and Canon 70-200 2.8 IS was 30 seconds @ f/2.8, 200 ISO. Hope that helps!
