The Heliopan 37mm RG 780 (87) Infrared Filter corresponds to a Wratten 87 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 37mm RG 780 (87) 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 88% of infrared light waves 780nm 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.

Q: 3. Would this work with a D5600?

A: This device is not compatible with the D5600.

Q: 4. Works with blackmagic pocket 4k

A: Unfortunately not, this will only be able to work with the Nikon D3100, D90 & D7000.

Q: 5. Will this work with the Nikon D4 ?

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

Q: 6. Will this work for monitoring in movie mode?

A: Presuming 'movie mode' refers to camera's playback of recordings saved to the data card, no it can't (stated on page 26 of user manual, a free PDF copy can be downloaded from the B&H site). Playback of images/recordings saved to the FreeWave's CCTB camera is possible, however.

Q: 7. Will this work for the Canon D7 Mark II? Thanks

A: I learned too late that it does not currently work with the 7D Mk II. Previous models of the Canon cameras use a mini USB to transfer the video, but the 7D uses a micro USB. B&H said the do not currently have a cable that will fit that configuration. Kudos to B&H for prompt phone service and a full refund.

Q: 8. 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: 9. 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: 10. This Item compatible with the Nikon D800 ?

A: Yes, it is.
