The Heliopan 27mm 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 27mm 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 27mm 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.

Related Questions and Answers

Q: 1. will this lens bundle with the xs10??

A: As of yet the XS10 is not bundled with the 27mm lens, it may be in the future.

Q: 2. I owned the original 27mm But one day it just died. When I went online to see if I could find out how to fix this problem, I found many people had their 27mm just stop working. Do you know if they fixed this problem with the new lens? It was a really great lens and gave wonderful results and did last for several years. It was the first lens I bought and even bought it from B&H before I bought the camera.

A: They did make quite a few improvements to the overall stability of this lens in terms of build quality and operation so you should get more longevity out of this lens when compared to the previous version.

Q: 3. What is the manual focusing experience like? For example, if I wanted to use manual focus for street photography, would it be difficult?

A: With the FUJIFILM XF 27mm f/2.8 R WR Lens. it's easy to use manual focus for stationary subjects but using manual focus on a moving subject will require patience, skill, and practice.

Q: 4. Can you mount filters and still use the stock hood?

A: While currently it hasn't been tested with this newly announced lens, based on the look of the the hood (seen here: https://bhpho.to/3j7ugXN) it seems the hood will screw into the filter threads. It might then be possible for you to screw the hood onto a filter with front threads, but until further testing is done when the lens is physically with us, it cannot be ascertained.

Q: 5. can you apply extension tube to this lens?

A: Yes an extension tube can be used with this lens, as it would only shorten the existing focusing distance of that lens. One example is the FUJIFILM MCEX-16 16mm Extension Tube for Fujifilm X-Mount, BH # FUMCEX16 https://bhpho.to/3oAShtj

Q: 6. Will this lens work on a XT-1?

A: Yes, the FUJIFILM XF 27mm f/2.8 R WR Lens is compatible for use on the FUJIFILM X-T1 Mirrorless Digital Camera.

Q: 7. Is this lens weather sealed?

A: The Voigtlander Ultron 27mm f/2.0 Lens is not weather sealed.

Q: 8. Hello. Is this lens compatible with the X-T50 firmware? TYIA

A: Yes, the Voigtlander Ultron 27mm f/2.0 Lens (FUJIFILM X, Black) is compatible with the Fuji X-T50. Please note that this lens features a manual focus design.

Q: 9. Will this lens be all metal? (The previous mki had plastic).

A: The majority of the lens is metal including the mount, there is some plastic but mostly metal.

Q: 10. If I use the accessory LH-FX27 lens hood, is there a cap that will work with that?

A: FUJIFILM LHCP-27 Lens Hood Cap https://bhpho.to/3AWnpst
