Designed to block both ultraviolet and infrared spectra, while allowing visible light to cleanly pass, the Formatt Hitech 82mm Firecrest UV IR Cut Filteris a specialty filter that helps to achieve accurate and precise colors with digital sensors. This unique filter also features a 15-layer Firecrest coating, which further serves to minimize surface reflections and maintain light transmission for consistent color accuracy and image acuity.

Due to sensors' increased sensitivity to infrared light, false colors can occur when photographing in difficult lighting conditions. This filter helps to only pass visible wavelengths in order to avoid unwanted color shifts for greater color accuracy and image clarity. This filter is constructed from optical glass for maintained image quality and is set in an aluminum filter ring. The SuperSlim ring measures 5.5mm-thick and its slim design helps to minimize the likelihood of vignetting. This filter features front threads to permit stacking of additional filters or the attachment of a lens cap.

UV IR cut filter blocks wavelengths at both sides of the visible spectrum in order to achieve a more pure transmittance and greater color accuracy.

The 15-layer Firecrest coating has been applied directly to the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multi-coating is water- and scratch-resistance for greater overall durability.

Firecrest coating attenuates UV and IR contamination, as well as surface reflections, for consistent light transmission and acuity.

Optical glass is used in order to maintain clear image quality with high contrast and color fidelity.

The aluminum alloy SuperSlim filter ring measures 5.5mm-thick and features front threads for stacking additional filters.

Related Questions and Answers

Q: 1. What is the IR cutoff? What wavelengths does the filter actually allow to pass through?

A: The Ice 77mm UV/IR Cut Filter cuts out UV Rays below 390nm, and cuts out IR Rays above 750nm. The filter has 99.4% light transmission between 400-700nm.

Q: 2. Can this filter be used with a VND filter to cut the IR ? Would you put this filter first on your lens or on top of all others?

A: Yes, filters are stackable on the Ice 82mm UV/IR Cut Filter as long as they are 82mm in diameter.

Q: 3. Can I use this circular filter placed on my lens and carry on a mattebox with square ND filters to avoid IR input? Or will it be better to buy square IRND filters for mattebox? I have little budget and I don't know what a better option.

A: If the mattebox fits on the camera lens with filter in place you could do it that way.

Q: 4. Hello, I've read a review telling that when using a UV/IR filter on WIDE Angle Lenses the image can be compromised: the interference varies with the angle of incidence of the light on the glass. This renders this filter unusable with wide-angle and even normal focal lenses, resulting in a greenish gradient from the center to the corners. - This was posted for the 72mm version of another brand's filterQ: Has someone else experienced this problem on Full Frame or APS-C DSLRs with Wide Angle Lenses like 16mm ?Thank you very much in advance!

A: UV/IR blocking filters work ideally for lenses with an aperture angle up to 60. The principle of such an interference filter is an aperture angle-dependent color influence that is dictated by physical principles, and as the angle of the incident light increases it drifts towards blue, i.e. for wide-angle lenses, from an aperture angle larger than 60, the color reproduction at the edge of the image tends to lean towards bluish.

Q: 5. will this filter work on a Canon 400mm f5.6 lens? will the filter interfere with the bayonet hood on the lens?

A: If you are referring to this lens, Canon EF 100-400mm f/4.5-5.6L IS II USM Lens, you should be fine using that filter with the hood.

Q: 6. Why do so many BMPCC6K Pro users use a UV/IR Cut Filter? Something to do with the sensor?

A: Some users want to cut IR light pollution more than the internal Black Magic IR filtration system can do.

Q: 7. Does this filter allow to directly photograph a solar eclipse without damaging de camera sensor?

A: No, an eclipse will certainly damage your sensor with this filter. You would need an strong nd filter at the very least, like a 25 stop nd.

Q: 8. Has anyone used one of these on a Sony A7s series camera? Both versions of the A7s come with a Low Pass filter, which I believe cuts down much of what this filter is intended to do, so is it irrelevant?

A: I haven't used it on a Sony and don't know their specs, but generally Low Pass filters don't cut UV, and don't cut all Infra Red. You can test by taking a photo of the IR cell on a TV remote while pressing one of its buttons, if the photo shows a light in the cell, IR is getting through. I normally use this lens for work where extreme sharpness or clarity is critical or when using tungsten lighting.

Q: 9. Does ir cut only serve to reduce red from sunlight or is this also necessary in artifificial light like LED?

A: LED white lights typically remove unused spectrums to save on power so the difference under artificial light should be minimal. The largest gains will be under sunlight and UV/IR specific lighting. Unless the camera is full spectrum modified you will likely see very little difference under any light but almost none under modern artificial lighting. I would not buy an IR cut filter unless the camera is full spectrum modified as your camera already has one built in and UV filters are much less expensive. HTH.

Q: 10. Does this sit furthest from the camera or closest to the camera when pairing with a Variable ND filter?

A: It really doesn't matter but typically a UV filter goes on the lens first.
