The Heliopan 30.5mm RG 830 (87C) Infrared Filter corresponds to a Wratten 87C 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 830 (87C) 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 830nm 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.

• Allows approximately 85% of infrared light waves beginning at 830nm to pass through
• Effective for infrared films or other media sensitive to infrared wavelengths 830nm 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

Q: 1. This Item compatible with the Nikon D800 ?

A: Yes, it is.

Q: 2. As a Nikon user, I notice that the models listed are older models of the D3xxx and D7xxx line. Will it also work with The D3300, D7100, and D7200?

A: This device is only compatible with the Nikon D3100, D90 & D7000.

Q: 3. Would this work with a D5600?

A: This device is not compatible with the D5600.

Q: 4. Will this work for t7i?

A: The Vello FreeWave Viewer VL Wireless Live View Remote Kit will work with the Canon T7i.

Q: 5. 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: 6. I want to buy one more CCTV camera transmitter only. (It possible to see from 4 cameras on one monitor). How to buy?

A: You can set the Receiver to control any one of up to four cameras outfitted with Transmitters that are set up within range of the Receiver. Unfortunately, though, it does not appear as though we carry the FreeWave Viewer VL Wireless Live View Remote separately.

Q: 7. 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: 8. 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: 9. 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: 10. Canon 7d compatibility ? will this work as a wireless live view remote on the Canon 7d ?

A: I use it on a Canon 5D mkII and it works fine. Only drawback is that it does not give autofocus on the trigger-button while in live view mode. The 7D mk1 is very much the same hence it should have the same drawback.I know that the 5D mkIII has autofocus on the trigger in live view so I suspect that 7d mkII would have that as well. Other than autofocus I have not experienced any compatibility issues.
