The Heliopan 36mm 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 36mm 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 36mm 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. Is this compatible with the Sony A9 and A7R series cameras?

A: Yes, fully compatible with the A9 and A7 series cameras.

Q: 2. Is this come with ring adapter that fit to Tonika 100mm ATX i 100mm macro? I am also wondering if it is compatible with Canon 5D mark III.

A: Yes. Both the Tokina AT-X Pro 100mm f/2.8 Macro lens and the Tokina atx-i 100mm f/2.8 FF Macro lens use 55mm filter threads. As the Bolt TTL Macro Ring Flash with Transceiver Set for Canon includes a set of lens adapters: 52, 55, 58, 62, 67, 72, 77mm, it includes the 55mm lens adapter designed for use with both Tokina 100mm lenses. The Bolt TTL Macro Ring Flash with Transceiver Set for Canon is compatible for use with Canon cameras, which would include the Canon EOS 5D Mark III DSLR camera.

Q: 3. Does the bolt VM-1000 work with Canon R5?

A: Bolt TTL Macro Ring Flash with Transceiver Set for Canon BH #BOVM1000C works with Canon EOS R5 Mirrorless Camera BH #CAER5.

Q: 4. How does the Transceiver attach to a Nikon D750, which has both a pop-up flash and hotshoe?

A: When the Bolt VM-1000 TTL Macro Ring Flash Transceiver is connected to the hotshoe of the camera, it will disable the pop-up flash and will operate as the only flash on the camera.

Q: 5. Do you have 100 mm lens adapter for this macro ring flash ?

A: Please verify if your lens focal length is 100mm or the filter size is 100mm.

Q: 6. why dont you include a NIKON version? or is either the cannon or sony unit, suitable for Nikon ?

A: Bolt discontinued the Nikon version. This Godox will work on Nikon if you get the Nikon transmitter separately. https://www.bhphotovideo.com/c/product/1652520-REG/godox_mf12_k2_mf12_macro_flash_2_light.html This is a Nikon transmitter. https://www.bhphotovideo.com/c/product/1468007-REG/godox_x2tn_x2_2_4_ghz_ttl.html

Q: 7. Is this compatible with Canon 6D Mark ii?

A: Yes, this is compatible with the Canon 6D Mark II. It will fire and also provide TTL exposure control.

Q: 8. It looks like the "modeling light" (located on top of the camera) is absolutely useless in focusing with any macro lens longer than pancake. Is there any way around this "limitation"?

A: Your best bet is to use additional Led's positioned on the sides and turn them on when needed to focus.

Q: 9. Will the Canon 67 Macrolite Adaptor fit this ring? The ones that come with the unit are not very good. Mine got stock to the filter.

A: No, i'm sorry, they are not compatible.

Q: 10. Will this system ever be available for Canon and/or Micro 4/3?

A: Bolt released a Canon version but the release may be premature. It does not sync below 1/200sec on my 5DM$ and my 6D does not recognize it as compatible. It looks like they may need more work on compatibility.
