The Heliopan 30.5mm RG 850 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 30.5mm RG 850 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 approximately 85% of infrared light waves 850nm 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 approximately 85% of infrared light waves beginning at 850nm to pass through
• Effective for infrared films or other media sensitive to infrared wavelengths 850nm 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 200x reduces exposure by about 7.6 stops
• Thin, brass filter ring helps to prevent vignetting, jamming, and provides additional strength
• 30.5mm front filter threads allow for use with other filters
• Plastic case for storage and transport

Related Questions and Answers

Q: 1. Would this work for the Sony A7iii? Looking at the cords it looks like it might

A: No, it only works with select Canon and Nikon cameras.

Q: 2. Has anyone that owns this had success in getting it to start/stop video? Mine does not, despite following instructions in the manual.

A: We are sorry to hear of your issue. There is report of another B&H customer having success with this on a Canon 5D Mark II. We would suspect that maybe the IR lamp is at fault. Make sure it is properly aligned. Contact The Gradus Group the distributor of this item for further assistance. If no avail and you have had this less than 30 days, contact B&H Customer Service for exchange or refund.

Q: 3. Will this work with a Cannon EOS 7 D ? Thanks

A: Yes, the Vello FreeWave Viewer VL Wireless Live View Remote Kit with AV/Shutter & Infrared Cables for Select Canon Cameras is compatible with the Canon 7d. It might not allow all features depending on the camera setting.

Q: 4. Is it compatible with Canon 90d?

A: Yes.

Q: 5. does it come with the np-60 battery charger?

A: The Vello FreeWave Viewer VL Wireless Live View Remote includes an AC USB wall adapter and a USB cable. The batteries are charged while in the unit. The transmitter and receiver are charged separately.

Q: 6. With a Nikon D200, when will the image appear on the viewer. Before, or after shutter release? I'm asking this because when I connect the D200 to a TV with the AV cord, the TV displays the image only after shutter release. Ie not real time live view. I want to use this for infrared photography when the through-the-lens image is invisible due to the infrared filter.

A: The D200 will act in the same way with this device as it does with your TV. What you are describing is a limitation of the D200.

Q: 7. Is this compatible with the Canon 5D Mark IV?

A: Unfortunately, no, the Vello FreeWave Viewer VL AV & Shutter Release Cable for Canon 6D, 7D, 5D Mark III, and 1D Mark IV, would not be compatible for use with the Canon EOS 5D Mark IV DSLR camera.

Q: 8. will it work on a Nikon D7000?

A: Providing the kit has a VEVCN 10 cable it will work on the D7000.A VEVCN 20 works on the D500.Thanks.

Q: 9. Will this work on a Canon 5DSr?

A: Yes, the Vello FreeWave Viewer VL Wireless Live View Remote Kit with AV/Shutter & Infrared Cables for Select Canon Cameras can be used with the Canon EOS 5DSR.

Q: 10. Will this work with the Nikon D4 ?

A: No, unfortunately this is not compatible with the Nikon D4 camera.
